Plugins Not Working

[souriz]

I've got Jellyfin set up on my Synology NAS using the jellyfin/jellyfin Image from Docker Hub installed through Container Manager, and *almost* everything is working exactly as it should. Everything except for plugins.

In the administration dashboard I can see my installed plugins all showing as active
   
but no metadata is loading for any of my files, and I cannot add any plugins through the catalogue.

My plugin catalogue shows nothing
   
despite the correct repos being loaded (I tried adding the unofficial just to see if it would change anything but it didn't)
   

In the system log, the following error is repeated for each media file:
[ERR] [##] MediaBrowser.Providers.TV.EpisodeMetadataService: Error in "TheMovieDb"
System.Net.Http.HttpRequestException: Resource temporarily unavailable (api.themoviedb.org:443)
---> System.Net.Sockets.SocketException (11): Resource temporarily unavailable

What have I done wrong?

Most of the time, this is caused by the host using IPv6 but Jellyfin doesn't have IPv6 enabled. Try enabling IPv6 in Jellyfin.

Also, are you using host or bridge networking?

I'm using bridge networking for the container, and don't have IPv6 set up. Is that a requirement?

[TheDreadPirate]

It isn't. But it is often the cause. Linux and Windows default to enable IPv6. Run this command on the host and in a bash shell in the container then share the output.

Code:

curl -vvv https://image.tmdb.org/t/p/original/uqIVJR1fmkiwpcIsIcV0vxiyY4z.jpg -o /tmp/futurama.jpg

I am having the same exact issue as the person who stopped responding to you.

I am running host via the jellyfin container on ugreen nas. I enabled IPV6 in jellyfin and rebooted jellyfin, but its still a no go.

Do I need to change it to bridge?

I ran the script above in the container terminal and got a lot of random stuff, but this is the readable part of the tail end of the output:

Very different I can see.

Your help is much appreciated.
