Can't access site proxied by traefik from docker container

I am able to access the sites from the serving machine, if I use the port number; for example http://localhost:8080 but if I try from outside my lan with url it won't work. I have a frontend rule for traefik that works, but it don't work for the other containers.

docker-compose.yml:

version: "2"
services:
  traefik:
    image: traefik:latest
    command: --api --docker --logLevel=DEBUG
    hostname: mysite.ddns.net
    restart: unless-stopped
    networks:
      - web
      - bridge
    ports:
      - 80:80
      - 8080:8080
      - 443:443
    labels:
      - "traefik.docker.network=web"
      - "traefik.enable=true"
      - "traefik.backend=traefik"
      - "traefik.frontend.rule=Host:${DOMAINNAME}; PathPrefixStrip: /traefik"

I have a Ghost-Blog and Home-assistant in separate ymls:

Ghost Blog Docker-Compose:

    hostname: mysite.ddns.net
    restart: unless-stopped

    labels:
      - "traefik.docker.network=web"
      - "traefik.enable=true"
      - "traefik.backend=ghost"
      - "traefik.frontend.rule=Host:${DOMAINNAME}; PathPrefixStrip: /blog, ${DOMAINNAME}"
      - "traefik.port=2368"
    volumes:
     - "/docker/ghost/blog:/var/lib/ghost/content"
    environment:
      - NODE_ENV=production
      - url=http://mysite.ddns.net

Home Assistent Docker Compose:

version: "2"
services:
  home-assistant:
    image: homeassistant/home-assistant
    container_name: home-assistant
    hostname: mysite.ddns.net
    privileged: true
    restart: unless-stopped
    networks:
      - web
      - bridge
    ports:
      - 8123:8123
      - 8943:8943
    labels:
      - "traefik.docker.network=web"
      - "traefik.enable=true"
      - "traefik.backend=home-assistant"
      - "traefik.frontend.rule=Host:${DOMAINNAME}; PathPrefixStrip: /hass"
      - "traefik.port=8123"
      #- "traefik.basic.protocol=http"
    volumes:
      - "/docker/home-assistant/config:/config"
      - "/etc/localtime:/etc/localtime:ro"
      - "/etc/timezone:/etc/timezone:ro"
    devices:
      - "/dev/bus/usb:/dev/bus/usb"

networks:
  web:
    external: true
  bridge:
    external: false

DOMAINNAME is defined and works in a .env file. I have opened ports 80, 443, 2368, 8123, 8080 in firewall and router.

Any suggestions?
