SOLVED: Jellyfin Media Player Linux never shows subtitles

[Host-in-the-Shell]

If you still have the flatpak installed it needs to be removed, as I suspect both services could be conflicting trying to run on the same port. Anyway, you can use the command

Code:

systemctl status jellyfin

to see if the server is running and what errors are happening. If not, you can start it with

Code:

sudo systemctl start jellyfin

and we can trouble shoot from there.
