Hello @softwarecrash and thanks for your interest in Traefik,

The error Could not define the service name for the router: too many services is raised when Traefik cannot automatically choose which service is attached to a router.

Even if you are configuring a redirect middleware a service needs to be attached to the iobroker, web, and jarvis routers. That's why Traefik is trying to configure a service automatically for the above routers and cannot infer one because of multiple service definitions.

Here is a fixed version of your configuration (noop@internal is a service which does nothing):

    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=proxy"
    ## iobroker
      - "traefik.http.routers.iobroker.entrypoints=http"
      - "traefik.http.routers.iobroker.rule=Host(`iobroker.my.domain.de`)"   
      - "traefik.http.middlewares.secure-https-redirect.redirectscheme.scheme=https"
      - "traefik.http.routers.iobroker.middlewares=secure-https-redirect"
      - "traefik.http.routers.iobroker.service=noop@internal" # <--- Fix Service configuration
      - "traefik.http.routers.iobroker-secure.entrypoints=https"
      - "traefik.http.routers.iobroker-secure.rule=Host(`iobroker.my.domain.de`)"  
      - "traefik.http.routers.iobroker-secure.tls=true"
      - "traefik.http.routers.iobroker-secure.tls.certresolver=http"
      - "traefik.http.routers.iobroker-secure.service=iobroker"
      - "traefik.http.services.iobroker.loadbalancer.server.port=8081"
      - "traefik.http.routers.iobroker-secure.middlewares=middlewares-authelia@file"

      - "traefik.http.middlewares.secure-https-redirect-web.redirectscheme.scheme=https"

      - "traefik.http.routers.web-secure.tls=true"
      - "traefik.http.routers.web-secure.tls.certresolver=http"

      - "traefik.http.services.web.loadbalancer.server.port=8082"

      - "traefik.http.routers.jarvis-secure.middlewares=middlewares-authelia@file"

Please note that instead of configuring a redirect middleware on each router, you can configure the redirection at the entrypoint level as explained in the following documentation: Traefik EntryPoints Documentation - Traefik

Hope this helps!
