<p>When I use this command: "kubectl get nodes" I get the below errors:</p>

<pre><code>Error from server (Timeout): the server was unable to return a response in the time allotted, but may still be processing the request (get nodes)
</code></pre>

<p>Can anyone help to solve this issue?</p>

<p>As OP @Sam.Yang informed in comment section problem is resolved.</p>
<p>Problem was in the wrong configuration of <code>KUBE_ETCD_VERSION</code> in <code>apiserver.sh</code>.</p>
