Docker Plex return 50-plex-update: saiu e não encontrou o servidor

Question

Eu tento executar a imagem oficial do plexinc/pms-docker Docker, mas os logs retornam isso:

[s6-init] making user provided files available at /var/run/s6/etc...exited 0.
[s6-init] ensuring user provided files have correct perms...exited 0.
[fix-attrs.d] applying ownership & permissions fixes...
[fix-attrs.d] done.

[cont-init.d] 50-plex-update: exited 0.
[cont-init.d] done.
[services.d] starting services

Tenho acesso ao my-ip: 32400 , mas o aplicativo não encontra o servidor (procurando em loop).

Você pode ver meu arquivo docker-compose.yml :

version: '3'

services:
    plex:
        image: plexinc/pms-docker
        container_name: plex
        hostname: plex
        restart: always
        network_mode: "host"
        ports:
            - 32400:32400/tcp
            - 3005:3005/tcp
            - 8324:8324/tcp
            - 32469:32469/tcp
            - 1900:1900/udp
            - 32410:32410/udp
            - 32412:32412/udp
            - 32413:32413/udp
            - 32414:32414/udp
        environment:
            - TZ=Europe/London
            - ADVERTISE_IP=http://${IP}:32400/
        volumes:
            - ${MOUNT_POINT}/plex-config:/config
            - ${MOUNT_POINT}/plex-config/transcode:/transcode
            - ${DOWNLOAD_PATH}:/data

Alguém pode me ajudar?
