Often, when trying to open a website, a secure connection error appears PR_END_OF_FILE_ERROR
Please let me know how to solve the problem and whether it is on the browser side or, for example, on the side of the AVAST antivirus program. Greetings, Marek

radi.stoyanov said Turns out the option DNS over HTTPS is what caused the problem.

cor-el said This usually means that Firefox wasn't able to find a cipher suites to use to connect to this server and reached the end of the list. There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.
You can check your browser and possibly compare this with the server setup. https://www.ssllabs.com/ssltest/viewMyClient.html
This could be a problem with your Avast security software.
You also have a user agent that is likely modified by Avast Anti-Track that could be causing issues, so if you use this software then try to disable it.
