Not the best solution but I will leave it in case no one else comments; maybe consider a different vpn provider that does not assign a port on every connection such as mullvad. You should be able to follow this example: https://github.com/JamesTurland/JimsGarage/blob/main/Torrent-VPN/docker-compose.yml

Thank you for the recommendation. I have been wanting to try out the FUTO apps (which grayjay) for a while but couldn’t find it on f-droid. It looks like they have their own repo which you need to add.

Just got grayjay downloaded and it is so good!

sailfish?
