Transmission

Running transmission inside docker with openvpn. I can download from https trackers like official Ubuntu images just fine. But I can't connect to any trackers that are udp or http. Errors in the log say "scrape error: connection failed (c:1279)" etc

Any thoughts?

Transmission supports http, https, and udp trackers.

It sounds like the trackers are simply overloaded. Regretfully that happens all too often these days, mostly due to DDoS attacks.

Try adding some trackers to the afflicted torrents.
