Can't connect to plex using localhost/IP

I’m new to this Docker Environment and my Linux skill is pretty basic. Though, I managed to install and run Radarr, Overseerr successfully. I have installed Plex successfully (I guess) but couldn’t connect through localhost or IP. I use Portainer and I’m on windows. I used Docker compose.

version: "2.1"
    container_name: plex
    network_mode: host
      - PUID=1000
      - PGID=1000
      - VERSION=docker
      - PLEX_CLAIM=myclaim-token
      - /var/lib/docker/volumes/plex_config/_data:/config
      - /var/lib/docker/volumes/plex_tv/_data:/tv
      - /var/lib/docker/volumes/plex_movies/_data:/movies
    restart: unless-stopped

Here is the log.

I can see the server through this but it says unable to connect securely.
I also notice there is no IP Address or Published Ports

Windows version - 21H2 OS build - 19044.1586
Docker Desktop version - 4.6.1 (76265)
Portainer version - 2.11.1

Please help!!!

You used: network_mode: host which would expose those on your host docker host, not the docker container. Which is why you don’t see them listed in Portainer. Did you try the IP of the computer and port 32400 in a web browser? That should load in the web browser on the same computer.

The message you’re getting in is about your server port not being open in your firewall which is another issue to tackle, but from what you say here, you did everything correctly, you just need port forward 32400 to whatever IP that Plex Server is hosted, for it to say it can connect securely.
