Sounds like Qt 6.11.x Network module behaves differently on SSL handshake failure.

I had a similar case. My workaround was to enable IgnoreSSLErrors. You can either go to Advanced in the menu and change the option (in this case, I turned off Wi-Fi), or, if that’s not possible, edit qBittorrent.conf:

...
[Preferences]
...
Advanced\IgnoreSSLErrors=true
...

This worked but, would this cause problems if it doesn't get fixed in the long run?

Well, it depends. It probably allows connections to or ignores self-signed certificates, so theoretically, it is a security risk. But there are HTTP trackers without SSL, and torrents have hashes that are checked on your side anyway. I didn't look into it further, but it seems to be a bug in Qt or qBittorrent. There are more details in the debug qt6-base log that I captured. Maybe it will help.

This is a qt bug. Expect a fix when qt fixes it and we upgrade.
