How to reproduce:
Run the following code from python:

from kubernetes import client
v1 = client.RbacAuthorizationV1Api()
v1.list_cluster_role_binding()

Same errors happen with list_cluster_role_binding_with_http_info().

My Kubernetes master (Minikube) is working and I can get the clusterroles with kuebctl get clusterroles
