Traefik returns the dashboard when using curl, but '404 not found' when call from browser

Traefik Traefik v3 (latest)

Hi, I'm having a particular problem about configuring traefik, where calling to "http://mydomain.com:8080/dashboard from browser returns a '404 not found'. Yet when I send a request through powershell command Invoke-WebRequest - Uri "http://mydomain.com:8080/" it returns a 200 code with the following content:

Which, I assume it is working fine

Here's my docker-compose.yml file:

  reverse-proxy:
    image: traefik:latest
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--entrypoints.web.http.redirections.entrypoint.to=websecure"
      - "--entrypoints.web.http.redirections.entrypoint.scheme=https"
      - "--entrypoints.web.http.redirections.entrypoint.permanent=true" # redirect http to https
      - "--certificatesresolvers.myresolver.acme.tlschallenge=true"
      - "--certificatesresolvers.myresolver.acme.email=${EMAIL}"
      - "--certificatesresolvers.myresolver.acme.storage=/letsencrypt/acme.json"
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    networks:

    environment:

    expose:
      - "8001"
    depends_on:
      db:

    labels:

      - "traefik.http.routers.api.rule=Host(`${DOMAIN_NAME}`)"
      - "traefik.http.routers.api.entrypoints=websecure"

      - "traefik.http.routers.api.tls.certresolver=myresolver"
      - "traefik.http.services.api.loadbalancer.server.port=8001"

Any help is appreciate!

Enable and check Traefik debug log (doc), are routers created? Enable and check Traefik access log in JSON format (doc), what’s the output during requests?

Thanks for the reply, I've checked the logs, but it shows no clue about the port 8080 configs, apart from the 'Static configuration loaded ...' line. Though I did see the dashboard service, if I'm not mistaken. Pardon me the timestamps, I should've turned of portainer's timestamp logging

Other services works as expected, its just the dashboard

I got it, after I added the labels, traefik can finally route to the dashboard.

  labels:
      - "traefik.enable=true"
      - "traefik.http.routers.dashboard.rule=Host(`dashboard.${DOMAIN_NAME}`)"
      - "traefik.http.routers.dashboard.entrypoints=websecure"
      - "traefik.http.routers.dashboard.tls=true"
      - "traefik.http.routers.dashboard.tls.certresolver=myresolver"
      - "traefik.http.routers.dashboard.service=api@internal"
      - "traefik.http.middlewares.dashboard-auth.basicauth.users=${DASHBOARD_AUTH_USERS}"
      - "traefik.http.routers.dashboard.middlewares=dashboard-auth@docker"```

In addition to that, I also had to change the 'api' service name to 'api-server'. I think Traefik might confuses which api service to use, its own internal 'api' or my 'api'

Note that this will create an insecure entrypoint on 8080 without auth - you should remove it.

Check simple Traefik example for best practice
