NGINX reverse proxy in front of Plex media server v1.3.3.3148

plex.nginx.conf

# This example assumes the NGINX proxy is on the same host as the Plex Media Server.
# To configure Plex Media Server to serve requests without requiring authentication,
# ensure that your LAN subnet is correctly added to the advanced server setting called
# "List of IP addresses and networks that are allowed without auth".  Example:
# 192.168.0.1/24

upstream plex-upstream {
  server 127.0.0.1:32400;
}

server {
  listen 80;
  server_name plex tv plex.example.com tv.example.com;

  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 or query argument.
    # This fixes a bug where you get permission issues when accessing the web dashboard.
    set $test "";

Working with Plex as of version 4.125.1

@afteroot which config are you looking for?

On which you get 502 error, maybe i can help you with config

I'm not sure which config you are referring. If you mean the nginx config it's the same config that is posted here. I drop it in place and got bad gateway.

@Bun-Bun , in that way you need to check that your upstream is correct

upstream plex-upstream {
  server 127.0.0.1:32400;
}
