title: Failed to reach erlang port mapper - Couchbase error
body: <p>I am having problem adding servers to a cluster or create reference to remote cluster in <strong>Couchbase</strong>. I've created to EC2 Windows 2008 servers on Amazon in the same region and zone. I've installed Couchbase on each machine and the server is running fine. I've opened all the ports in the Security Groups just for testing.</p>
  
  <p>When I try to add a server I get the following error in the 'Add Server' window:</p>
  
  <blockquote>
    <p>Attention - Failed to reach erlang port mapper. Timeout connecting to
    "54.243.156.39" on port "4369". This could be due to an incorrect
    host/port combination or a firewall in place between the servers.</p>
  </blockquote>
  
  <p>I've used the same username and password on both. The connection problem happens even when I want to add a server to a current cluster when I first configure the server. </p>
  
  <ul>
  <li>I've installed the <strong>couchbase 2.0 beta</strong></li>
  <li>the EC2 servers aren't in cluster, they are single EC2 machines</li>
  </ul>
  
  <p>Any help on this.</p>
