I am testing a openshift v3 starter (ca-central-1) and created a project from custom docker image stream (from github). It was running fine, but after I changed a config map, rescaled the deployment to 0 pods, upscaled it to 1 pod, openshift can no longer start any pods.

The error in web interface is (in Events tab):

Failed create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container 
for pod "hass-19-98vws": Error response from daemon: grpc: the connection is unavailable.

Pod sandbox changed, it will be killed and re-created.

These messages appear in a endless loop. I tried to deploy new deployment but it gives same logs. What am I doing wring?
