Plex Nginx Reverse Proxy

This configuration will allow you to serve Plex via Nginx.

Minimal Requirements

Nginx

Plex:

• Remote Access - Disable
• Network - Custom server access URLs = https://<your-domain>:443,http://<your-domain>:80
• Network - Secure connections = Preferred.
• Note you can force SSL by setting required and not adding the HTTP URL, however some players which do not support HTTPS (e.g: Roku, Playstations, some SmartTVs) will no longer function.

Optional Requirements

UFW or other firewall:

• Deny port 32400 externally (Plex still pings over 32400, some clients may use 32400 by mistake despite 443 and 80 being set).
• Note adding allowLocalhostOnly="1" to your Preferences.xml, will make Plex only listen on the localhost, achieving the same thing as using a firewall.
