Dashboard returns 404

Traefik Traefik v2

Whenever I try accessing the dashboard either via HTTP or HTTPS (either via Google Chrome or curl) I'm met with a 404 page. I've searched through multiple other community threads/GitHub issues with no result whatsoever (Please bear in mind I'm quite new to Traefik). The docker-compose section (focusing on traefik service for brevity purposes) is the following:

version: "3.8"
services:
  proxy:
    container_name: proxy

See simple Traefik example.

Did you check the Traefik logs for error?

Hello @bluepuma77,

First of all thanks for taking the time to answer me. Yes, I have already checked the logs but sadly I've found nothing to pinpoint the issue. I have already tried the docker-compose file you pointed out but I gave it another shot, with no result whatsoever. Let me clarify that all other services are reachable from their respective subdomains using https (http-to-https redirection also seems to be working fine). Here's my updated docker-compose file (again only the proxy section for brevity purposes):

version: "3.8"
services:
  proxy:
    container_name: proxy
    image: traefik:v3.0
    ports:
      - "80:80"
      - "443:443"
    restart: always
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /var/log:/var/log
      - network-certificates:/certificates
    environment:
      DUCKDNS_TOKEN: <TOKEN>
    command:
      - --api.dashboard=true
      - --log.level=DEBUG
      - --log.filepath=/var/log/traefik.log
      - --accesslog=true
      - --accesslog.filepath=/var/log/traefik-access.log
      - --providers.docker.network=network
      - --providers.docker.exposedByDefault=false
      - --entrypoints.web.address=:80
      - --entrypoints.web.http.redirections.entrypoint.to=websecure
      - --entryPoints.web.http.redirections.entrypoint.scheme=https
      - --entrypoints.websecure.address=:443
      - --entrypoints.websecure.asDefault=true
      - --entrypoints.websecure.http.tls.certresolver=le
      - --certificatesresolvers.le.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory
      - --certificatesresolvers.le.acme.email=billsioros97@gmail.com
      - --certificatesresolvers.le.acme.storage=/certificates/acme.json
      - --certificatesresolvers.le.acme.dnschallenge=true
      - --certificatesresolvers.le.acme.dnschallenge.provider=duckdns
      - --certificatesresolvers.le.acme.dnschallenge.resolvers=1.1.1.1:53,8.8.8.8:53
      - --certificatesresolvers.le.acme.tlschallenge=true
    networks:
      - network
    healthcheck:
      test: ["CMD", "traefik" ,"healthcheck"]
      interval: 30s
      timeout: 3s
      retries: 30
    labels:
      - traefik.enable=true
      - traefik.http.routers.mydashboard.rule=Host(`dashboard.<SUBDOMAIN>.duckdns.org`)
      - traefik.http.routers.mydashboard.service=api@internal
      - traefik.http.routers.mydashboard.middlewares=myauth
      - traefik.http.middlewares.myauth.basicauth.users=test:$$apr1$$H6uskkkW$$IgXLP6ewTrSuBkTrqE8wj/

I included the DuckDNS related sections as it didn't seem to work without them!

Is healthcheck working? It looks strange, check with docker ps if container gets healthy.

Thank you very much! It seems the healthcheck was messing up traefik and I assume it was filtering itself as an unhealthy service or something of that sort...
