Unable to connect to WebUI when using macvlan

[PinguCloud]

Hey, so this is my compose:

services:
  docking-station:
    image: loolzzz/docking-station
    container_name: docking-station
    restart: unless-stopped
    # environment:
    #   - WEB_PORT=3000
    #   - SERVER_PORT=3001
    # Port mapping is not needed with macvlan
    # ports:
    #  - 3000:3000
    networks:
        macvlan:
          ipv4_address: 192.168.1.125
    volumes:
      - /data/docker/docking-station/config:/config
      - /data/docker/docking-station/data:/data
      - /data/docker/docking-station/logs:/logs
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime:ro
      # you should add mount points for each containers' docker-compose file you intend on update using this tool
      # i usually put everything in a single neat folder under
      - /var/lib/docker/volumes/portainer_data/_data/compose:/mnt/compose-files

networks:
  macvlan:
    name: MVLAN-Server
    external: true

And this is the container-log:

The only obvious thing seems to be that the web service wants to listen to ipv6 (only?) instead of ipv4.

Thanks for having a look! :)
