Jellyfin local IP detection with Cloudflare

[TheDreadPirate]

Using a non-standard port helps hide your server from script kiddies and port scanning. Instead of using port 80 or 443, use something like 50443. Low effort script kiddies and port scanners will only scan common service ports and won't bother scanning EVERY port.

Also, hiding available users from the Jellyfin login screen reduces the likely-hood of an attacker locking an account before fail2ban triggers.
