An error occurred while establishing a secure connection: several typical situations and methods for troubleshooting

Sometimes, and often enough, users when they try to log on to a particular Internet resource receive a message stating that an error occurred while establishing a secure connection. How to fix such a malfunction is now and will be considered. Depending on the situation, several different techniques can be used.

What does it mean: "An error occurred while establishing a secure connection"?

First of all, the problem of such a failure should be clearly understood. The essence of the error lies in the fact that when you access a particular site, you need to check the SSL certificate used to connect HTTPS to authenticate the publisher.

However, it is possible to clearly identify several situations in which such a test results in a negative result, as a result of which a message is issued that an error has occurred when establishing a secure connection:

• Inconsistency of the date and time on the computer with Internet parameters;
• Outdated or expired certificate;
• A certificate with an incorrect serial number;
• OCSP server errors;
• Incorrect browser settings (most often Mozilla Firefox);
• Blocking from the antivirus side.

Let's consider some typical situations.

An error occurred while establishing a secure connection: how to remove it in the simplest way?

Let's start with the most primitive way to fix the problem. As it was said above, the time set on the computer may not correspond to the Internet parameters. Therefore, these settings need to be changed.

Some users try to set the date and time directly in Windows, this does not give the desired result, and the error when establishing a secure connection appears again. Why? Yes, only because the setting needs to be done in the primary BIOS input / output system. That's when you can count on something else.

Disabling SSL and installing a certificate in the antivirus software

Antiviruses, in comparison with a firewall or Windows defender, are much more likely to block such connections, considering the connection unreliable.

The solution to the problem can be either temporary disabling protection, which is not very convenient, or setting the appropriate parameters. As a rule, such a partition is in network settings. Here you need to disable SSL verification, and then use the Certificate Installation Wizard, which will evaluate the reliability of the connection, after which you just need to install the certificate. After confirming the successful installation, the problem should disappear.

Fix a bug in browsers using the Mozilla Firefox example

With browsers, the matter is somewhat more complicated. As a rule, the message that an error occurred when establishing a secure connection is most often given out by the "fiery fox".

The situation can be corrected as follows. First, when the browser is disabled, go to "Explorer" in your profile set for the browser (the profile folder is on the system drive in the directory with the user name of the Users directory, where you need to go to the AppData directory, then - Roaming, then Mozilla, then Firefox , After that - Profiles, finally - ) and in the final directory delete the file cert8.db (the folders are hidden, so initially you need to enable the display of such objects). Next, just launch the browser, a warning page appears about the unauthenticity of the connection, then click on the line that states that the user understands all the risks.

Note: Additionally, in the security settings of tls_tickets, you can double-click to change the value of the parameter to false. Just in case, you can check whether the blocking extension AdBlock is enabled.

Problems with torrent trackers

Torrent trackers, as you know, the governments of many countries do not spoil much, considering that such sites host exclusively pirated content. This is partly true, but not always. One such resource is the NNM.Club tracker. An error occurs when establishing a secure connection on it often enough.

The tracker itself is now serviced exclusively at two addresses - 81.17.30.22 and 193.201.227.16. If pinging addresses results in something else, then spontaneous redirection occurs. In this case, you just need to clean the DNS cache, see if there are any entries for these addresses in the HOSTS file at the very bottom of the text; finally, you can simply set the IP exclusion rules for these IPs in the antivirus or in the firewall.

In an extreme case, if it is problematic to make it to the ordinary user or the solution does not help, instead of the torrent file you need to download the so-called magnet link and run it in the corresponding torrent program. In principle, the same applies to other trackers.
