Unable to connect to trackers from behind wireguard vpn - works behind openvpn

[lowest]

Hi all - I've been running Transmission Daemon 2.94 in Docker for a while now. I use OpenVPN client in the container and on a server I connect through. It all works well.

I'm trying to move to wireguard, and Transmission no longer works - every torrent reports

Code: Select all

[2019-12-31 21:35:25.704] TorrentName Could not connect to tracker (announcer.c:996)

And all torrents are red in the client.

I'm using the same base container (ubuntu 16.04) with the same packages except for excluding openvpn and including wireguard.

From within the container (docker exec -it my_container /bin/bash) I can make outgoing TCP and UDP connections with no issues as the user that transmission runs as.

Any ideas how I can debug this further?
