Thanks for pointing this out! I probably would have missed this, since I didn’t expect such a change for a patch release.

Their documentation mentions:

For jellyfin to know which reverse proxy is trusted, the IP, Hostname or Subnet has to be set in the Known Proxies (under Admin Dashboard -> Networking) setting.

Does this really mean, that the only way to configure this is through the web UI? This is kind of a problem when deploying it, since without the reverse proxy I can’t reach the Jellyfin server. Is there no way of doing this outside the web UI, via a config file or something?
