I'm not sure if this is a docker problem, although I came across a guy with the same problem and he also uses Transmission docked, so let's see...
Yesterday I saw Transmission not downloading anymore and I realised that the disc was full, so I freed around 140GB of space yet Transmission is stuck at not downloading (but it's seeding fine).
I purposefully added a file with a ton of seeds but nothing happens: it says 0 of 502 seeds connected and 0 of 49 peers connected and no error message, all this while seeding without problems. I tried stopping and restarting the Transmission service from portainer and also rebooted openmeidvault but it's still stuck, what can I do?
