I've tried just about anything. last week, I could download some torrents via the non-ssl tracker, and have been seeding them since, but that doesn't work since the connection to the tracker keeps timing out.

then, only after logging in on the website and restarting rtorrent it suddenly connects again. do I have to log in, like, every day to be able to seed? that never used to be the case, and my setup hasn't changed since I joined in 2008 (dammit, that's a long time now… :))

I had this problem too. it is because of an expired intermediate certificate from sectigo, that expired may 30th. you can check then certificate chain here

https://www.sslshopper.com/ssl-checker.html#hostname=https://tracker.gaytorrent.ru/

most modern software handles this expiration by skipping to the next one in the chain, but older software doesn't, so it fails. to fix this, you need to remove or disable the certificate on your local machine. on most linux distros, you can edit  /etc/ca-certificates.conf and prefix the certificate with a ! to disable its use. so change

mozilla/AddTrust_External_Root.crt

to

!mozilla/AddTrust_External_Root.crt

save, and run

update-ca-certificates

to update the certificate store. it should return with a notice that one certificate was removed.

on BSD systems, you will have to remove the certificate from your certificate store by hand, on OpenBSD that is /etc/ssl/cert.pem.

hope this helps.
