Jellyfin docker no longer can access files

I’ve been getting a lot of this type of error using Jellyfin in a docker container. Have no idea what triggers it, but I need to manually restart the container to get things going again. This has happened a few times. Once this happens, I can no longer playback files (either via the web interface, or kodi)

I’m on version 10.3.7

That’s really weird - I’m pretty sure we bundle a container with FFmpeg…

Well it normally works - this may happen after a few days of running.
