Used to sail the high seas in the days of TPB and Demonoid (when they were still good). Started again recently with a servarr stack with Deluge on docker but didn't realize it wasn't seeding properly and now my torrentleech ratio is in grave danger.

What might I be missing in my network config? Docker has all ports exposed and Deluge has uPnP enabled. Downloads work just fine and torrents periodically connect to peers but nothing ever actually uploads.
