title: How to rejoin consul clients to server after server restart?
body: <p>I have started server (single node).
  And joined client.</p>
  
  <pre><code># consul members
  Node                   Address             Status  Type    Build  Protocol  DC
  v-ansible              172.16.10.11:8301   alive   server  0.5.2  2         dc1
  v-php-cron             172.16.10.217:8301  alive   client  0.5.2  2         dc1
  </code></pre>
  
  <p>Then I restart server.
  And on server I see:</p>
  
  <pre><code># consul members
  Node                   Address            Status  Type    Build  Protocol  DC
  v-ansible              172.16.10.11:8301  alive   server  0.5.2  2         dc1
  </code></pre>
  
  <p>On client:</p>
  
  <pre><code># consul members
  Node                   Address             Status  Type    Build  Protocol  DC
  v-php-cron             172.16.10.217:8301  alive   client  0.5.2  2         dc1
  v-ansible              172.16.10.11:8301   left    server  0.5.2  2         dc1
  </code></pre>
  
  <p>An in client logs:</p>
  
  <pre><code>2015/11/05 17:35:05 [INFO] consul: adding server v-ansible (Addr: 172.16.10.11:8300) (DC: dc1)

  2015/11/05 17:40:30 [ERR] agent: failed to sync remote state: No known Consul servers
  </code></pre>
  
  <p>Why server stay in left Status?
  How can I rejoin clients to server automatically ?</p>
