Securing Traefik Dashboard unsuccesfull

Traefik Traefik v3 (latest)

Hi All,

I have been struggling a few days now. I am trying to secure my Traefik dashboard however I keep getting an error that there is not certificate and it's serving the default one. My containers can succesfully get a certificate from Traefik.

This is my docker-compose.yaml:

services:
  reverse-proxy:
    image: traefik:v3.3.6
    command:
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--providers.docker.network=traefik"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--api.dashboard=true"
      - "--certificatesresolvers.cloudflare.acme.email=**EMAIL REDACTED**"
      - "--certificatesresolvers.cloudflare.acme.storage=/etc/traefik/acme/cloudflare-acme.json"
      - "--certificatesresolvers.cloudflare.acme.dnschallenge.provider=cloudflare"
      - "--certificatesresolvers.cloudflare.acme.dnschallenge.resolvers=1.1.1.1:53,8.8.8.8:53"
      - "--log.level=DEBUG"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.dashboard.rule=Host(`traefik.vsv1.**DOMAIN REDACTED**`)"
      - "traefik.http.routers.dashboard.service=api@internal"
      - "traefik.http.routers.dashboard.entrypoints=websecure"
      - "traefik.http.routers.dashboard.tls=true"
      - "traefik.http.routers.dashboard.tls.certResolver=cloudflare"
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    environment:
      - CF_DNS_API_TOKEN
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./certs:/etc/traefik/acme:rw
      - ./config/traefik.yaml:/etc/traefik/traefik.yaml:ro
    networks:
      - traefik
    restart: unless-stopped

networks:
  traefik:
    external: true

My traefik.yaml looks like this:

global:
  sendAnonymousUsage: false

  insecure: false

    address: :80

      storage: "/etc/traefik/acme/cloudflare-acme.json"
      caServer: 'https://acme-v02.api.letsencrypt.org/directory'
      keyType: EC256
      dnsChallenge:
        provider: cloudflare
        resolvers:
          - "1.1.1.1:53"

providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
    network: traefik

My logs look like this:

I also seem to notice this in the log:

You can't have Traefik static config in traefik.yml and command:, decide for one (doc).

Maybe compare to simple Traefik example.

Issue was resolved by renaming my docker traefik container to the name traefik was showing as not configured.
