Plex showing Docker network instead of IP

Plex Media Server
,
1

Server Version#: 1.28.0.5999
Player Version#:

Whenever I go to (https://)watch.mydomain(.)com/, my connection appears as unsecure remote. I understand that Docker essentially NATs the connections through it’s own network but I have been able to see WAN and LAN IPs how they should be expected. I can’t figure out what has happened for this to stop working.

All connections appear as the Docker network (found by running ‘docker network inspect root_default’). It started in the 172.x.x.x range and I assume from so many restarts, it is now in the 192.168.64.x/20. My local network is 192.168.45.0/24.

I have a VPS that I Reverse SSH tunnel to avoid opening ports:

ssh -fN -R 80:localhost:80 -R 443:localhost:443 mydomain(.)com

I am using Caddy as the reverse proxy and here is the config:

#Plex reverse proxy
watch.mydomain(.)com {
        reverse_proxy localmachine(.)lan:32400
}

...

This is my compose file:

services:
  caddy:
    image: caddy:latest
    container_name: caddy
    restart: always
    environment:
      - PUID=1000
      - PGID=1000
      - UMASK=002
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./configs/caddy/config:/config
      - ./configs/caddy/data:/data
      - ./configs/caddy:/etc/caddy
  plex:
    image: hotio/plex:latest
    container_name: plex
    restart: always
    ports:
      - "32400:32400"
    environment:
      - PUID=1000
      - PGID=1000
      - UMASK=002
    environment:
      PLEX_CLAIM:  #(https://)plex(.)tv/claim
      ADVERTISE_IP: (http://)localmachine(.)lan:32400,(https://)watch.mydomain(.)com:443
      ALLOWED_NETWORKS: 192.168.45.0/24,10.189.78.0/24
    volumes:
      - ./configs/plex:/config
      - /mnt/data/media/movies:/media/movies
      - /mnt/data/media/tv:/media/tv

...

The Custom Server Access URLs in Plex are:

http://localmachine(.)lan:32400,https://watch.mydomain(.)com:443

I have flopped back and forth changing from http and https in the Access URLs and occasionally I am able to get a secure local connection if I connect by (https://)localmachine(.)lan:32400/ however, this is not consistent and I have trouble reproducing.

I can’t think of anything else to try and have already blown out my server and restarted a new one and tried a new distro without anything different happening. I have tried using network_mode: host and got the same results.
