This is my Plex Nginx configuration file.
Works exceptionally well, only port 80 and 443 are allowed on the router.
The caveat is that “Remote Access” will always show as unavailable, but this will still work. Make sure to add “yourdomain.com:443” to Custom server access URLs in Plex network settings.
