ansible k8s module failing to connect to cluster with 503

I’m trying to use ansible new k8s module (based ok k8_raw from 2.6) to maintain an aks k8 cluster. While I can work with the cluster with kubectl , any command with the k8s cluster fails with a 503 error.

For example this task:

- name: deploy kured daemonset
  k8s:
    state: present
    context: "{{ cluster_name}}"
    host: "redacted"# tried specifying this, but does not helo
    kubeconfig: "~/.kube/config"
    src: "aks/utils/kured-ds.yaml"

I suspect I’m missing something with configuring how to connect to the cluster

And failure:

Last few days, I crake my head on this and I believe I can able to help you :

Thanks, this does not seem to work for me, seems that the client appends version/openshift to the http request -which won’t work because this isn’t an openshift installation :frowning:
Can you please share what openshift version is installed in your system? and what ansible? Maybe it’s this kind of quirk
