Plugin Error: Name does not resolve (raw.githubusercontent.com:443)

[outkst]

What happens when you remove "IPv6 Address: accept_rtadv" from the container settings?

That is just a placeholder; IPv6 is not used at either the TrueNAS or Jellyfin jail level(s). With that said, the IPv6 interface is given a link local address of FE80::/10 by default. As far as I can tell, this is built-in to the kernel and cannot be explicitly disabled.

root@jailJellyfin:~ # ifconfig

What is strange is I have once been able to get the Plugins Catalog page to populate, and even installed a few of the plugins, after repeatedly restarting the Jellyfin jail and browsing to the plugins page. It worked one time, and I cannot replicate it no matter how many times I try to restart the server.

Even after installing, any plugins that need to communicate with web servers fails with the same "Name Does Not Resolve" issue.
