I was never a huge fan of those binhex containers assuming that’s what you’re using. Updates become a chore for maintainers when containers try to do too much and they also become responsible for making sure everything works together. Also, just me, but I don’t like the idea of funneling other traffic that needs a vpn through a container that is tightly coupled to my torrent client.

Recommend trying a standalone transmission container and using a gluetun container’s network. https://docker-compose.de/en/gluetun/
