Reverse Proxy for Jellyfin

 As I wanted to be able to access Jellyfin on the go, I needed to put it behind my reverse proxy.

Jellyfin Changes

Tell Jellyfin that it is behind a proxy so it will ignore the proxy ip and log the correct ip

• https://jellyfin.home.arpa:8920
• hamburger menu -> Networking
• Add the IP of your reverse proxy to "Known Proxies"
• Restart Jellyfin

Reverse Proxy

• Add the below to your NGINX config:

    location = /jellyfin {

        return 301 $scheme://$http_host/jellyfin/ ;

    }

    location /jellyfin/ {

        auth_basic off;

        proxy_pass https://jellyfin.home.arpa:8920/;

        proxy_buffering off;

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-Proto $scheme;

        proxy_set_header X-Forwarded-Host $http_host;

        proxy_set_header X-Forwarded-Port $server_port;

    }

    location /jellyfin/socket {

        # Proxy Jellyfin Websockets traffic

        auth_basic off;

        proxy_pass https://jellyfin.home.arpa:8920/socket;

        proxy_http_version 1.1;

        proxy_set_header Upgrade $http_upgrade;

        proxy_set_header Connection "upgrade";

        # proxy_set_header Host $host;

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_set_header X-Forwarded-Proto $scheme;

        proxy_set_header X-Forwarded-Protocol $scheme;

        proxy_set_header X-Forwarded-Host $http_host;
