have you tried Deluge? It's just like utorrent only better and without the cruft. Even comes with a WebGUI to use. I used to use utorrent and 100% switched to Deluge.
Plus there's both a plugin AND a docker container for deluge. Pick your poison as both are heavily updated/kept current.
Sorry, thought I mentioned it but obviously not. I am using deluge right now, but it has a quirk/bug in that the incoming port keeps getting "blocked". If I do the active port test, I get a warning. If I change the port, it then works, or if I restart the docker then the original port works again (so it's not my router, and I've done other testing to make sure it's not my router). I can't have a torrent docker where the port stops working often and I can't seed.
I might however try the plugin, thanks.
