I have Docker installed with Portainer, on Ubuntu Sever 20.4 running on a home media machine.
I have setup Docker, Portainer in addition to Nginx Proxy Manager and Jellyfin which I am to act as my own in-house media (ideally when I’'m outside my home connection too).
Some kind people have been helping on Reddit with this issue, which I believe might be related to my Jellyfin setup. The reason I say this, is if I visit my domain on my mobile using my data connection, I see a message about retrying for a live version.
It also says: “This page mydomain is currently offline”.
In the URL I see domain/web/index.html#!/selectserver.html
This is my Jellyfin container:
