Is it mandatory to have same certificate for kube api server and aws elb ? I changed the server key in kube-proxy config map with aws elb url. After that in master node, journalctl -xe gives an error from kubelet component stating certificate is not valid. If I replace the server back to masters ip it works again.

Version is 1.9.3

I have mapped aws elb's 443 port to redirect to api server's 6443 port.
