SOLVED: Plugin Manifest Error

[xenodius]

I updated the firmware on my QNAP and performed a complete factory reset, but I still have this problem. Jellyfin hangs on start after failing to access the plugin manifest. My other 13 containers work perfectly fine. I tried using curl on some addresses in various containers, and despite being connected to the same virtual adapter, my Jellyfin container doesn't have internet access but everything else does. (e.g. curl http://www.google.com and curl https://repo.jellyfin.org/files/plugin/manifest.json both fail) I'm not sure why updating Jellyfin using the same compose file would break network connectivity, but at least I have a problem to investigate.

EDIT: Previously, I used

Code:

docker image prune

instead of

Code:

docker system prune -a

, after stopping the container, running the latter prune, and restarting it works just fine. Thanks TheDreadPirate!
