You want to look into v2ray for self hosting. For example with https://github.com/hiddify/Hiddify-Manager

Did not work wit gpodder2go, so I installed https://github.com/kd2org/opodsync (docker: https://github.com/ganeshlab/opodsync) again. That seems to work.

I have been using https://github.com/oxtyped/gpodder2go for a while, seems to work and I have not found a better solution yet.

Still looking for a web or desktop podcast player that does sync with gPodder though…

I did not agree to anything. When I open the site they just start serving videos to me (even autoplay is activated by default). If they don’t want me to watch their videos without ads they should stop serving them to me (ie, put them behind a paywall)
