How do I link Jelly to a dedicated Website where anybody can login?

[teledyn]

1) Get a domain, if you don't already have one.  You can buy one from a reputable registrar or use a free DDNS service like DuckDNS or NoIP.
2) Setup port forwarding for ports 80 and 443 to the server running Jellyfin.
3) Setup a reverse proxy on your server.  We have guides for Caddy, Nginx, Apache, and Traefik.  I recommend Caddy since that is the simplest.
4) Get a certificate via Let's Encrypt.  Caddy can automate this process.
5) ???
6) Profit!

I have done all this, and everything works on the LAN, but from the outside world I get:

Code:

[font=monospace][color=#000000][Mon Aug 19 18:19:17.753816 2024] [proxy_http:error] [pid 618922:tid 618953] [remote 72.143.[/color]
201.81:58788] AH01114: HTTP: failed to make connection to backend: 192.168.0.13

[/font]
and the Android client times out. This is using the example networking/apache config from the install docs with letsencrypt certificates, and with that same .13 IP as the SERVER_IP and in the jellyfin networking.xml as a KnownProxy.
