Context

So I've been trying to setup open-webui behind a reverse proxy, in this case Traefik.

As you can see from the screenshot, this is the page I'm greeted with when accessing webui.
I simply don't understand as to why I'm getting this error when I point Traefik at the internal 8080 port of open-webui?
If I were to uncomment the ports part and visit the site with ip and port specified (e.g. chat.bss:8081), then it works perfectly fine

docker-compose.yaml

  chat-webui:
    build:
      context: ../apps/chat_open-webui/.
      args:
        OLLAMA_BASE_URL: '/ollama'
      dockerfile: Dockerfile
    container_name: chat-webui
    # ports:
    #   - "8081:8080"
    volumes:
      - chat-webui:/app/backend/data
    restart: unless-stopped
    depends_on:
      - traefik
    networks:
      - ai-network
    environment:
      OLLAMA_BASE_URL: http://ollama:11434
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.chat-webui.entrypoints=web"
      - "traefik.http.routers.chat-webui.rule=Host(`chat.bss`)"
      - "traefik.http.services.chat-webui.loadbalancer.server.port=8080"

Environment

Open WebUI Version: [latest]
Operating System: [Ubuntu 22.04]
