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;
	}
}

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 X-Plex-Device $http_x_plex_device;
            proxy_set_header X-Plex-Device-Name $http_x_plex_device_name;
            proxy_set_header X-Plex-Platform $http_x_plex_platform;
            proxy_set_header X-Plex-Platform-Version $http_x_plex_platform_version;

            proxy_redirect off;

            proxy_set_header Host $http_host;

            proxy_pass http://plex-upstream;
    }

thanks

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.
