Add TLS1.3 Support (draft 28) ("Secure connection failed" error on amtrak.com) #2155
Steps to reproduce
The website opens
"Secure Connection Failed" error
Relevant forum thread https://forum.adguard.com/index.php?threads/28363/
Very odd issue indeed. I can reproduce it and it is caused by AdGuard for Windows/Mac.
I have a portable Firefox that's not filtered by AG for Windows (and has been added to AG for Windows' exclude app in advanced settings so it's not filtered by AG for Windows at all) and the page loads up fine. In my main Firefox install that AG for Windows filters, it doesn't load (secure connection error).
Adding amtrak.com to the HTTPS exclusions does work, but I'm wondering if there's some other bug/issue here.
