title: gcloud kubectl failing to connect to Kubernetes API Endpoint
body: <p>I've setup a cluster in Google Container Engine and according to the Console, the API Endpoint for it seems to be completely different than the public APIs of either master or nodes in the cluster (which I thought was weird).</p>
  
  <p>When trying the <code>gcloud</code> command line tool to manage the cluster, all commands issued with <code>cloud preview container kubectl</code> fail with a timeout reaching the API Endpoint.</p>
  
  <p>I've tried changing Network Firewall rules and nothing seems to work.</p>
  
  <p>I was trying to follow the <a href="https://cloud.google.com/container-engine/docs/guestbook" rel="nofollow">guestbook</a> tutorial to deploy my Docker instances in the Kubernetes managed GKE cluster and am currently stuck on not being able to issue any commands against the cluster.</p>
  
  <p>Any ideas of what could be wrong?</p>
