title: How to fix etcd cluster misconfigured error
body: <p>Have two servers : <code>pg1: 10.80.80.195</code> and <code>pg2: 10.80.80.196</code></p>
  
  <p>Version of etcd : </p>
  
  <pre><code>etcd Version: 3.2.0
  Git SHA: 66722b1
  Go Version: go1.8.3
  Go OS/Arch: linux/amd64
  </code></pre>
  
  <p>I'm trying to run like this :</p>
  
  <p>pg1 server :</p>
  
  <pre><code>etcd --name infra0 --initial-advertise-peer-urls http://10.80.80.195:2380   --listen-peer-urls http://10.80.80.195:2380   --listen-client-urls http://10.80.80.195:2379,http://127.0.0.1:2379   --advertise-client-urls http://10.80.80.195:2379   --initial-cluster-token etcd-cluster-1   --initial-cluster infra0=http://10.80.80.195:2380,infra1=http://10.80.80.196:2380   --initial-cluster-state new
  </code></pre>
  
  <p>pg2 server :</p>
  
  <pre><code>etcd --name infra1 --initial-advertise-peer-urls http://10.80.80.196:2380   --listen-peer-urls http://10.80.80.196:2380   --listen-client-urls http://10.80.80.196:2379,http://127.0.0.1:2379   --advertise-client-urls http://10.80.80.196:2379   --initial-cluster-token etcd-cluster-1   --initial-cluster infra0=http://10.80.80.195:2380,infra1=http://10.80.80.196:2380   --initial-cluster-state new
  </code></pre>
  
  <p>When trying to cherck health state on <code>pg1</code>:</p>
  
  <pre><code>etcdctl cluster-health
  </code></pre>
  
  <p>have an error :</p>
  
  <pre><code>cluster may be unhealthy: failed to list members
  Error:  client: etcd cluster is unavailable or misconfigured; error #0: client: endpoint http://127.0.0.1:2379 exceeded header timeout
  ; error #1: dial tcp 127.0.0.1:4001: getsockopt: connection refused
  
  error #0: client: endpoint http://127.0.0.1:2379 exceeded header timeout
  error #1: dial tcp 127.0.0.1:4001: getsockopt: connection refused

  Both servers run on virtual machines with <strong>Bridged Adapter</strong></p>
