External Host with SSL Backend

Hi everybody,
i now play around a little while with traefik and i really like it.
but now i have a little problem. i try to forward traffic to a backend witch is https at this moment. so i build a file witch is like that:

http:
  routers:
    unifi:
      rule: Host(`xxx.xxxx.xx`)
      entryPoints:
        - "web-secure"
      service: service1
      tls:
        certresolver: myhttpchallenge


  services:
    service1:
      loadBalancer:
        servers:
          - url: "https://192.168.xxx.xx:8443"

so but i have the problam that i am not able to reach the desternation app.
what did i do wrong?
can somebody help me?
thanks and kind regards
Matze

For everybody how is searching for a solution.
add this to your container command or config:

  • --serverstransport.insecureskipverify=true`
    than the backend will work fine!
