nginx config for proxying requests for plex over a hostname-based virtualhost.

nginx.conf

upstream plex-upstream {
	# change plex-server.example.com:32400 to the hostname:port of your plex server.
	# this can be "localhost:32400", for instance, if Plex is running on the same server as nginx.
	server plex-server.example.com:32400;
}

server {
	listen 80;

	# server names for this server.
	# any requests that come in that match any these names will use the proxy.
	server_name
		tv
		plex
		tv.example.com
		plex.example.com;

	# this is where everything cool happens (you probably don't need to change anything here):
	location / {
		# if a request to / comes in, 301 redirect to the main plex page.
                # but only if it doesn't contain the X-Plex-Device-Name header
		# this fixes a bug where you get permission issues when accessing the web dashboard
		if ($http_x_plex_device_name = '') {
			rewrite ^/$ http://$http_host/web/index.html;
		}

		# set some headers and proxy stuff.
		proxy_set_header X-Real-IP $remote_addr;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_redirect off;

		# include Host header
		proxy_set_header Host $http_host;

		# proxy request to plex server
		proxy_pass http://plex-upstream;
	}
}

I used Doonga's Headers but I'm not sure if it mattered. I used the orginal config in this gist but had to change proxy_pass http://plex-upstream; to proxy_pass http://plex-upstream/;

Notice the trailing / at the end? That made it work for me. Now when ever any one visits my URL they get plex and do not have to enter the port or the url.

This configuration forces me to log into Plex account from LAN. So I can reach the Web GUI only from localhost. I'm running Plex Server 1.1.4.2757.
Am I the only one having this weird thing going on?

Had some problems setting this up for plex, couchpotato, sabnzbd etc.

Problems seem to have been fixed by changing:

upstream plex-upstream {
    server localhost:32400;
}

to:

upstream plex-upstream {
    server 127.0.0.1:32400;
}

Hey all,

After a few hours of hacking and testing, I was able to get Plex Media Server v1.3.3.3148 working behind an NGINX reverse proxy on my local LAN, without it prompting for any authentication. Here is my gist with the configuration.

The key was the following configuration, which forces plex to see the request as coming from an IP in the whitelisted network:

    proxy_set_header        Host                      $server_addr;
    proxy_set_header        Referer                   $server_addr;
    proxy_set_header        Origin                    $server_addr; 

Hope this helps others!

Having some problems with downloading (not streaming) movies from Plex, using this Nginx configuration.
The downloads stop after exactly 1024MB.
Any else tried to download something from their Plex server behind Nginx?

Edit: This is a Plex bug, I think.

So I am having this same problem on latest version of plex and version 1.10.2 of nginx.

Here is my code:

`upstream plex-upstream {
# change plex-server.example.com:32400 to the hostname:port of your plex server.
# this can be "localhost:32400", for instance, if Plex is running on the same server as nginx.
server asm-tv-pc01.me.local:32400;
}

server {
listen 80;

    # server names for this server.
    # any requests that come in that match any these names will use the proxy.
    server_name
            tv
            plex
            tv.example.com
            plex.me.local;

    # this is where everything cool happens (you probably don't need to change anything here):
    location /plex {
            # if a request to / comes in, 301 redirect to the main plex page.
            # but only if it doesn't contain the X-Plex-Device-Name header
            # this fixes a bug where you get permission issues when accessing the web dashboard
            if ($http_x_plex_device_name = '') {
                    #rewrite ^/$ http://$http_host/web/index.html;
                    rewrite /plex(/.*) $1 break;
            }

            # set some headers and proxy stuff.
            # Plex headers
            proxy_set_header X-Plex-Client-Identifier $http_x_plex_client_identifier;

            proxy_set_header Host $http_host;
            proxy_set_header        Host                      $server_addr;

            proxy_pass http://plex-upstream;
    }

Did you ever get it working @andrewm659 ?

Update: The original gist without the proxy_set_headers as mentioned in follow-ups works well.
Thanks @spikegrobstein.
