On Cluster Import: websocket: bad handshake (returns 401)

1

Rancher versions:
rancher/rancher-agent:alle

Infrastructure Stack versions:

kubernetes (if applicable): v1.10.2

Setup details: (single node rancher vs. HA rancher, internal DB vs. external DB)

Single node behind Traefik inside docker swarm with lets encrypt

Steps to Reproduce:

I am trying to import a Kubernetes Cluster.

  1. I had the Problem, that the APIEndpoint IP for the Kubernetes API was set to the cluster internal IP.

I Fixed it by adding the External IP of the Kubernetes API via KUBERNETES_SERVICE_HOST Env in all Container inside the Import YAML generated bei Rancher:

https://rancher.integration.???.de/v3/import/…yaml

Now I am getting:
time=“2018-09-19T15:53:54Z” level=info msg=“Connecting to proxy” url=“wss://rancher.integration.???/v3/connect”
time=“2018-09-19T15:53:54Z” level=error msg=“Failed to connect to proxy” error=“websocket: bad handshake”
time=“2018-09-19T15:53:54Z” level=error msg=“Failed to connect to proxy” error=“websocket: bad handshake”

I already checked:

  1. wss connection(is Reachable but returns 401)
  2. Certificates (are valid)

What are the next Steps i can do to fix this Problem?
