SOLVED: Reverse Proxy

[TheDreadPirate]

You don't have remote access enabled.

Code:

<EnableRemoteAccess>false</EnableRemoteAccess>

That was it! I also changed the proxy targets to 127.0.0.1 and although the logs complained about this on restarts of jellyfin, apache and php-fpm, the service works, and works via remote as well. A thousand thanks for this, I missed that step in the installation!
