My Dashboard loads for ever and huge CPU spikes

Hey :wave:,

I just started using traefik everything seams to work but I got issues with the Dashboard which loads forever. It also comes with huge CPU spikes and when it loaded successfully everytime it tries to refresh the data of the Dashboard the spikes continue. I sadly have no clue what this could cause. My first guess would be a wrong config but I'm not sure if that's the case.

docker-compose:

version: "3.9"

services:

  traefik:
    # Use the latest v2.6.x Traefik image available
    image: traefik:v2.6
    container_name: traefik
    ports:
      - "80:80"
      - "443:443"
    restart: always
    env_file: .env
    labels:
      # Enable Traefik for this service, to make it available in the public network
      - traefik.enable=true
      # Use the traefik-public network (declared below)
      - traefik.docker.network=traefik-public
      # Define the port inside of the Docker service to use
      - traefik.http.services.traefik-dashboard.loadbalancer.server.port=8080
    volumes:
      # Map the dynamic conf into the container
      - ./traefik/config.yml:/etc/traefik/config.yml:ro
      # Map the static conf into the container
      - ./traefik/traefik.yml:/etc/traefik/traefik.yml:ro
      # Mount the volume to store the certificates
      - traefik-public-certificates:/etc/traefik/certs
      # Add Docker as a mounted volume, so that Traefik can read the labels of other services
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /var/log/traefik:/var/log/traefik
    networks:
      # Use the public network created to be shared between Traefik and
      # any other service that needs to be publicly available with HTTPS
      - traefik-public

volumes:
  # Create a volume to store the certificates, there is a constraint to make sure
  # Traefik is always deployed to the same Docker node with the same volume containing
  # the HTTPS certificates
  traefik-public-certificates:

networks:
  # Use the previously created public network "traefik-public", shared with other
  # services that need to be publicly available via this Traefik
  traefik-public:
    external: true

The only thing I could find out was that by removing admin-auth middleware from Traefik router the application loads again without spikes and any issues but I still have no clue what I'm doing wrong or how I can get basicAuth to work
