Current Behavior

New setup using PROTONVPN - Transmission does download, but feels a bit slow. Seeing "the gateway does not support nat-pmp" error message in logs, and am guessing issue might be failed port forwarding set up?

Edit: verified that transmission sees the port as closed.

Appreciate your assistance!

Expected Behavior

Port forwarding automatically happens.

How have you tried to solve the problem?

Turned on uTP in Transmission settings, no help.

Update: did some more searching using error strings, and found this link: https://www.reddit.com/r/ProtonVPN/comments/vnez5y/has_someone_looked_how_to_use_natpmp_with/

With this quote: "Note: OpenVPN is also supported. You just need to add +pmp at the end of your OpenVPN username. Then use a regular NATPMP client to get a port mapping."

And indeed, adding "+pmp" (without quotes) at the end of my OpenVPN username fixed the issue. Just sharing in case this helps anyone else, or you want to add to the documentation. Thanks for your work on this container!
