Where does that user: 30000:30002
come from?
Also that PUID/PGID seems wrong for a standard config.
Here’s mine:
jellyfin:
image: jellyfin/jellyfin
container_name: jellyfin
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/London
volumes:
- /opt/jellyfin/config:/config
- films:/data/movies
- tv:/data/tvshows
- jellyfinmeta:/config/metadata
ports:
- 8096:8096
restart: unless-stopped
Try dropping the user and changing your PUID and PGID back to 1000 and see how you get on.
I would start the investigation there.
I’m running my Jellyfin on a Raspberry Pi, and it runs like a dream, so there’s definitely a config issue afoot.
