I'm using Traefik with Kubernetes and want to deploy multiple sites with a letsencrypt wildcard cert. The logs show that the part of the requesting certificates seem to work fine, also the debug messages show that the cert should be used

time="2018-11-14T10:16:08Z" level=info msg="legolog: [INFO] [*.my-domain.com] Server responded with a certificate."

time="2018-11-14T10:16:08Z" level=info msg="Server configuration reloaded on :443"

But as I open the website and change from i.e. http://dashboard.my-domain.com to https://dashboard.my-domain.com I get an error that there is no cert and it is "ERR_SSL_PROTOCOL_ERROR" in Chrome.

To provide some Context here are my yaml snippets:

apiVersion: v1
kind: Service
metadata:
 name: traefik-ingress-service
 namespace: traefik
spec:
 selector:
 k8s-app: traefik-ingress-lb

also my Configmap looks like this:
