For Chromecast device users

If you are using Google Chome to stream your tabs through your Chromecast device, after launching your browser, you may see the message “The domain with which an encrypted connection is being established cannot be guaranteed.” Click Proceed.

If the message appears again, update your Kaspersky Lab application to patch E version 19.0.0.1088:

1. Start updating the databases of the Kaspersky Lab application.
2. After updating, restart your computer.

To make sure that the patch has been installed, open a Kaspersky Lab application and in the lower left part of the window, click Support... In the window that opens, you will find the full version number of the program, to which the letter will be added e.

What to do if the message appears again

If restarting the program did not help, send a request with detailed description problems in technical support Kaspersky Lab:

• Via My Kaspersky for Kaspersky Internet Security, Kaspersky Anti-Virus, Kaspersky Total Security, Kaspersky Security Cloud. See the Help for instructions.
• Via the Management Console of Kaspersky Small Office Security for Kaspersky Small Office Security. The instruction is in the help.

If you receive a message about a problem with the certificate when loading a site, it means that the site may be insecure. Attackers can steal your credentials and other information. We do not recommend opening such a site.

Certificate - digital signature site, which provides an encrypted connection between the user and the site, and also confirms the authenticity of the site.

If you are confident that this site is safe, click Proceed or I understand the risk and want to continue.

If you do not want such messages to appear, disable the encrypted connection scan or add to the exceptions the site, upon loading of which this message appears. How to do this, see the instructions below.

Reasons for the message

• The certificate may be revoked. For example, according to the owner's statement, if his site has been hacked.
• The certificate was issued illegally. The certificate must be obtained at the certification center after passing the check.
• The certificate chain is broken. Certificates are verified along the chain from the self-signed to the trusted root certificate, which is provided by the certification authority. Intermediate certificates are for signing (validating) another certificate in the chain.
  Reasons why the certificate chain may be broken:
  • The chain consists of one self-signed certificate. Such a certificate is not certified by a certification authority and can be dangerous.
  • The chain does not end with a trusted root certificate.
  • The chain contains certificates that are not intended to sign other certificates.
  • Root or intermediate certificate expired or not expired. The certification center issues a certificate for a certain period of time.
  • The chain cannot be built.
• The domain in the certificate does not match the site to which the connection is established.
• The certificate is not intended to prove the identity of a site. For example, a certificate is only intended to encrypt the connection between a user and a site.
• Certificate usage policies violated. Certificate policy is a set of rules that determine the use of a certificate with specified security requirements. Each certificate must comply with at least one certificate policy. If there are more than one, the certificate must satisfy all policies.
• The structure of the certificate is broken.
• An error occurred while verifying the certificate signature.

How to remove messages about a problem with a certificate by disabling encrypted connections verification

Disabling scan of encrypted connections will lower the level of computer protection.

If you do not want a Kaspersky Lab application to display a message about a problem with a certificate, disable encrypted connection scanning:

1. To find out how to open the program, see the instructions in the article.

1. Go to section Additionally and select Network.

1. Select an option Do not check secure connections.

1. Read the warning and click Proceed.

Checking encrypted connections will be disabled.

How to remove messages about a problem with a certificate by adding a site to exceptions

It is possible to add a site to the exclusion from scanning encrypted connections in Kaspersky Anti-Virus, Kaspersky Internet Security, Kaspersky Total Security versions 18 and later, and Kaspersky Small Office Security 6 and later. In more early versions this function is not available.

1. Go to section Additionally and select Network.

1. Click Configure exclusions.

Mozilla Firefox has long established itself as a reliable and stable browser. In the event of any malfunctions or vulnerabilities, it warns the user by displaying appropriate notifications on the screen. One of these is "your connection is not secure" in Firefox. How to fix this and access the site, read the article.

What does notification mean?

The message "Your connection is not secure" appears when you try to go to a web resource with a secure connection, for which Firefox was unable to verify certificates. Since the check failed, the Internet browser warns that the connection may be dangerous and blocks entry to the site using this notification.

Sometimes, the browser can block the connection of popular sites, for example yandex.ru or youtube.com. If you trust the site, and for some reason the browser has blocked it, you can turn off this notification.

How to disable?

If your notification appears on several sites, do the following manipulations.

Check the correct time in Windows 10:

Disable SSL inspection

Antiviruses can intercept connections for eavesdropping and monitoring while Firefox tries to process this data as well. Accordingly, there is no way for the browser to check the correctness of the certificates. To protect the user from potential threats, he replaces the web page with the message "Your connection is not secure". To eliminate the conflict between the antivirus and the browser, disable the SSL and HTTPS protocol checking function:

1. Avast. Go to Settings → Active Protection and click on Configure next to Web Shield. Then uncheck "Enable HTTPS Scanning" and click OK.
2. Kaspersky. Go to "Settings" → "Advanced" → "Network" and in "Scanning encrypted connections" check the box "Do not scan encrypted connections". Then click OK.
3. ESET. Go to settings and disable / enable "SSL / TLS" protocols, and click OK.

Deleting the certificate store file

The possibility of damage to the certificate file cannot be ruled out. For the browser to generate new file, first you need to remove the damaged old one.

Nowadays, it is quite difficult to find a person who would not use the Internet.

Many users spend quite a lot of time on its open spaces. Therefore, more than ever in demand.

But what to do if all plans are violated by a warning that suddenly appears your connection is not secure.

In this article, we will look at why given error in different browsers and what to do if it appears.

Content:

The first step is to consider the occurrence of this problem during use.

The meaning of such a message

Often this message appears when visiting secure sites. Such sites when interacting with fireFox browser use a special encryption method - #encryption. This is done in order to exclude the possibility of viewing the transmitted information by intruders.

To understand that you are visiting exactly such a site - pay attention to the line displaying the address of the visited page. In the status line ( #status_Bar) a secure site will display a closed padlock icon. It will also be displayed in address bar (#lokation_bar).

In addition, the browser will display and domain name site in the status bar, highlighted in yellow. This is necessary so that the user cannot be fooled with the purpose.

Such sites may contain not only protected information, but also unprotected information to which everyone has free access.

If the site's information is unprotected, FireFox will display a lock icon crossed out by an oblique line in the status bar. The domain name will also be missing in the address bar and status bar. If you pay attention to such information, you can immediately understand that the site you are visiting has partial protection.

To solve it, you will need to reinstall the antivirus or disable interception of protected connections in its settings.

For example, if you are using to protect the system - open "Settings" and go to the tab "Active protection".

There you will need to click on the "Configure" button located next to the web shield.

In the window that opens, uncheck the selection box from the line Enable HTTPS Scanning... In conclusion, it is necessary to confirm the changes in the settings by clicking on the "Ok" button.

If you are using a product such as - you will need to follow these steps:

• open a window with antivirus settings;
• in the lower left part of this window, click on the "Settings" button;
• use item "Additionally"to go to the "Network" tab;
• deselect the menu bar "Scan encrypted connections";
• tick the parameter "Do not scan encrypted connections";
• confirm the changes by clicking the "OK" button.

It is not difficult to find the information you need for other antivirus products on the Internet.

Lack of trust in the certificate, your browser can display not only on little-known sites, but also on such giants as Google. Most often, owners may encounter this. This is because the Microsoft family settings found in user accounts are activated.

The next step is to delete all existing family members using the function "Remove from family" on the advanced options tab.

In conclusion, you should also leave the family yourself, using the parameter of the same name.

The fourth mistake

It lies in the lack of trust in the certificate, since the latter is self-signed.

These types of certificates are designed to protect against eavesdropping, but do not provide any information about the recipient.

Most often, non-public sites use this, so you can easily bypass this warning.

Fifth mistake

It consists in the fact that the certificate provided to you belongs to a completely different Internet resource.

This problem occurs quite often, primarily due to the fact that the issued certificate is valid for one part of the visited site.

For example, you visited https: /example.com and received a warning about a similar error, and a certificate was issued for https: / www example.com. If you go to the last one, no warnings will appear.

Certificate store

The occurrence of such messages can also occur due to file corruption cert9.dbthat stores all your certificates.

In this case, without opening FireFox, delete the above file so that it will be restored the next time you start it.

To do this, follow these steps:

• open the menu and select the "Help" item;
• go to tab "Information for problem solving";
• open the profile folder located in the section "Application Information";
• open the menu again and select "Exit";
• highlight the file db and remove it;
• restart your browser.

When is it possible to ignore warnings?

This option is suitable if you are confident in the reliability of the resource.

However, even in this case, you are not immune from eavesdropping and interception of confidential data by unauthorized persons.

If you nevertheless decide to ignore the warning that appears, follow a few simple steps.

On a page with a similar warning, use the button "Additionally".

If the browser connects to a site with weak encryption, load it using the outdated security system. You will be provided with the possibility of such download. In the case of a resource whose certificate is unverified, add it to the exceptions.

Error reporting capability

There are quite a few sites on the Internet that make it possible to report an error to your center.

To do this, check the box at the bottom of the issue record page, next to the line "Report bugs like this to help Mozilla and block malicious sites."

An unsecured connection warning appears in the browserChrome

Problems with the certificates of certain sites opened by the Chrome browser are identical to those of FireFox and can be solved by similar methods.

The reasons for their occurrence should also include:

In the first case, to eliminate the error, you will need to correct the system date and time so that they match those set on the server. To do this, open the tab for the time and date settings, and adjust them.

A warning due to an unverified or outdated certificate most often occurs when you try to enter your personal account on this or that resource.

To get around this, click on the tab in the error display window "Additionally"and then use the button "Go to the site".

Blocking extensions are more related to the antivirus program installed on the computer.

To fix this situation you will need to open chrome browser and go to the installed extensions tab.

Select your modules from the list of available ones and uncheck the checkbox.

After that, reopen your browser and try to visit the site.

This error may also be due to a crash in Chrome. A banal reinstallation of the browser can fix the situation.

To remove the faulty version, open the window "Programs and Features", select a title installed browser and click the "Delete" button.

After the application has been removed, restart your computer and re-run google installation Chrome.

In most cases, the insecure connection warning stops bothering you.

Conclusion

This article has come to an end, in which we examined the options for the appearance of a warning about the presence of an unsecured connection.

We hope that the available information will be useful to you and will help you in solving this error.

Your connection is not secure how to fix:

Secure sites on the Internet can be recognized by the abbreviation HTTPS (Hypertext Transport Protocol Secure) and the green security marking on the left side of the browser address bar - this is the encryption of data exchange between the site with all modules and the browser. In addition, the server presents a valid certificate before starting data transfer. This way, users can be sure that they are opening the "correct" site, and not a fraudulent attacker.

However, this is an all-or-nothing approach: the server transmits data either completely encrypted over HTTPS, or completely unencrypted over HTTP. But there are often cases when only a part of the site is encrypted, for example, if it contains ads that are transmitted over HTTP, or uses scripts that again access HTTP resources. This leads to problems in HTTPS: browsers display warnings, block or incorrectly display sites. In such cases, opportunistic encryption (OE, Opportunistic Encryption) offers a way out.

Opportunistic encryption

Opportunistic Encryption (OE) is an important intermediate solution between HTTP and HTTPS. This method, if necessary, allows you to encrypt the transmission of site data over HTTP. A side effect of using OE is that site data can be transferred over HTTP / 2 at higher speeds.

Increasing the share of secure connections
Google regularly estimates that Chrome users are increasingly sharing data over HTTPS.

HTTP encryption

OE is a method currently established by the Internet Engineering Task Force project. The bottom line is as follows: to transfer data from HTTP sites, the TLS (Transport Layer Security) cryptographic protocol is used. It looks like HTTPS only at first glance, so when using OE, the "HTTPS" mark is not visible in the address bar.

In order to catch the difference, you need to compare the establishment of the connection between the browser and the server over HTTPS and OE and analyze the behavior of the browser. On the right page, we offer a schematic description of how both methods work. HTTPS is designed to be secure from the outset and is triggered immediately along with a specific browser request to establish an encrypted connection.

If the server cannot install it, the communication ends with an error notification before it actually starts. From a security point of view, this is the right decision, since data transmission in unencrypted form cannot be carried out over HTTPS.

OE works differently. The browser requests an unprotected HTTP site from the server on port 80. Through the so-called alternative service, a simple additional header, the server responds to the browser that it can transmit data from a similar site not only through port 80, but also through port 443 using TLS. If the browser supports OE (currently only Firefox), the following requests can be made over TLS.

As with HTTPS, the browser first checks the server certificate, then the encryption key is exchanged, and only then a secure connection is established between the browser and the server. But, unlike HTTPS, if the encryption fails, the data transfer is not interrupted - there is a transition to unencrypted communication, as the browser originally requested from the server.

Technically, the difference between HTTP with TLS and HTTPS in terms of requests is not the strength of the encryption, but only the letter S in the address bar. The difference lies in the establishment of a connection to the site and in the fact that browsers make HTTP and HTTPS connections differently: an encrypted HTTP connection, as opposed to HTTPS, can have questionable mixed content, for example, links to HTTP resources or ads that transmitted only in clear text.

Speed \u200b\u200bcomparison: accessing a site over HTTP and HTTP / 2

The speed of the HTTP / 2 protocol is much faster, as tests show, but the data transmission channels are still protected by HTTPS. HTTP connections over HTTP / 2 only allow OE.

More speed, less security

Opportunistic encryption can be safely thought of as a gap-filling tool until all sites have switched to HTTPS - a process that will take years. Meanwhile, OE can be used to increase the communication speed. For HTTP / 2, the second version of the HTTP protocol, encryption is required. HTTP / 2 transfers data from secure sites, and the speed of sites increases (see right), but only for those sites that support HTTPS. Since OE runs on HTTP sites, the data from such sites can also be transmitted over the faster HTTP / 2 protocol.

Until all sites have switched to HTTPS, opportunistic encryption is a practical workaround.

When it comes to security, OE doesn't do all the work. This method can be used to protect against passive eavesdropping, for example, by special services that monitor network traffic in general. An active attack only needs to intercept the first header in which the server offers an alternative service. As soon as this indication is removed, the process of establishing encryption is interrupted and it becomes possible to listen to an unsecured channel.

OE does not represent an alternative to HTTPS - on this its proponents do not even insist. Skeptics also point out that OE is a great reason for site administrators not to switch to HTTPS. But in reality, it turns out not quite so: often the listed technical reasons the transition is prevented.

Will HTTPS completely disappear?

Even the inventor got involved in the discussion about encryption on the Internet World wide web Tim Berners-Lee. He advocated moving away from HTTPS altogether - not in the sense of ending encryption, but on the contrary: he suggested using real-time TLS cryptography for all network traffic - then there would be no need to separate HTTP and HTTPS.

Three methods of accessing websites

Check-in The browser and website communicate either over an unencrypted channel over HTTP, or over an encrypted channel over HTTPS, or using the new Opportunistic Encryption over HTTP encryption method.

HTTP

With a standard HTTP request, the browser contacts the server and sends a request over an unencrypted channel, to which the server responds without authentication, also in clear text.

HTTPS

Before even a bit of payload is sent, an encrypted connection is established between the browser and the server over HTTPS. This method includes authentication.

New: Opportunistic encryption

Opportunistic encryption begins with an unencrypted request. Encryption is set only when the server sends an alternate header with an offer to encrypt the channel.

There is a danger here: with the help of a middleman attack, an attacker can intercept the alternative header (see main text)

SoftEnter VPN Client program.

In connection with the real threat of the expansion of the punitive functions of the "Antipiracy Law" and the possible beginning of its transfer to ordinary users, namely, the possible introduction of fines for downloading pirated content (movies, music programs, and so on), I continue to acquaint visitors of my sites with information about how to avoid these penalties, that is, how to download from the Internet ANONYMOUS. Earlier, I showed you how to download anonymously from direct links and from torrents. In this article, we will look at one of the ways how to encrypt all Internet traffic. Encrypting all Internet traffic will allow you to become completely anonymous on the Internet by changing your IP address to a third-party one. After changing the IP address using the application proposed in this article, none of the outsiders will be able to find out what sites you visited, what you downloaded, including your Internet traffic in the torrent client will be encrypted.
This is an application called SoftEnter VPN Client. This is a client program for communicating with a service called VPN Gate.
VPN Gate is an experimental project of the Graduate School of the University of Tsukuba (Japan). The idea of \u200b\u200bthe project is the organization by volunteers of a public public network of VPN tunnels that are created using a special software, and are provided free of charge to the public. Anyone can connect to them.
Private public vPN networks Gate is provided by ordinary people, not companies, and even the hypothetical possibility of obtaining logs (the history of the sites you visited and the download history) at the request of the competent authorities is excluded. The VPN Gate service was created in order to enable citizens of countries where certain sites are blocked freely and anonymously to visit them, but the service can also be used to download the content you need without fear of unpleasant consequences.
Setting up the SoftEnter VPN Client is not difficult at all. Now I'll show you how to do it.

First, download on the developer's website from the link archive with installation file SoftEnter VPN Client software.

By the way, information for those who have already used universal instant German Nano Kleber glue and for those who are not yet familiar with our product - our glue has changed dramatically.
Naturally for the better. First, has changed appearance packaging and bottles of glue. Secondly, the volume of the bottles has increased by a third! Now the weight of the bottle is 31.5 grams, the bottle with welding granulate is 25 grams.
And most importantly, the quality of the glue itself has been improved. By popular demand from customers, the glue became thicker. This allows you to work with it without rushing before squeezing (gluing). The preparation period is doubled! However, its price remained the same.
You can learn more about the Nano Kleber glue on our official website at the link. You can also order it there. Delivery - all over Russia.

After downloading the archive, unpack the folder with the installation file to your desktop.

Open it and launch the installation of the SoftEnter VPN Client software.

After installing the SoftEnter VPN Client software, we launch it.

We select one of the VPN servers and connect to it.

After connecting to the selected vPN server all your internet traffic will be forwarded through a third-party server, reliably hiding your internet activity.

You can easily find out that you are connected to the VPN server of your choice by visiting one of the IP address checking services. It's easy to find them. In the search line of any search engine, for example, in Yandex, we write search phrase "Ip check".

Disconnecting your VPN connection is easy. After installing the SoftEnter VPN Client software, a special icon will appear in the tray. Click on it right click mouse and in the dropped context menu select the bottom line to disable the program.

As you can see, encrypting all your internet traffic using SoftEnter VPN Client and VPN Gate is a snap.
In the near future we will continue to study the topic of encrypting Internet traffic and consider another way to encrypt traffic using vPN services, directly, without using third party applications, but only by changing the Internet connection settings.
