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;

  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.

@afteroot which config are you looking for?

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

I'm glad this is still proving helpful!

Working with Plex as of version 4.125.1

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;
}
