Server Version#: 4.145.1  
Player Version#: Web

Hi,  
my question about strange problem i have for a long time with different versions of plex server - a lot of errors in browser like “[Connections] [Loopback] is unavailable at [http://127.0.0.1:32400](http://127.0.0.1:32400) …”

Why web app is trying 127.0.0.1 when i access web interface from non local host?

My setup is just docker-compose:

```auto
services:
  plex:
    container_name: plex
    image: plexinc/pms-docker
    network_mode: host
    restart: unless-stopped
 # ports:
 # - 32400:32400/tcp
 # - 8324:8324/tcp
 # - 32469:32469/tcp # DLNA
 # - 1900:1900/udp
 # - 32410:32410/udp # local network discovery
 # - 32411:32411/udp # local network discovery
 # - 32412:32412/udp # local network discovery
 # - 32413:32413/udp # local network discovery
 # - 32414:32414/udp # local network discovery
    environment:
      - PLEX_CLAIM= ****
      - ADVERTISE_IP=http://192.168.1.5:32400
      - ALLOWED_NETWORKS=192.168.0.0/20
 # hostname: box.lan
    volumes:
      - /mnt/store/plex/config:/config
      - /mnt/store/plex/transcode:/transcode
      - /mnt/store/plex/data:/data

```

Also i have problems with posters (some of them missing) and maybe all these problems come from misconfiguration in my setup?

Thank you.
