title: OpsCenter is having trouble connecting with the agents
body: <p>I am trying to setup a two node cluster in Cassandra. I am able to get my nodes to connect fine as far as I can tell. When I run nodetool status it shows both my nodes in the same data center and same rack. I can also run cqlsh on either node and query data. The second node can see data from the first node, etc.</p>
  
  <p>I have my first node as the seed node both in the Cassandra.yaml and the cluster config file. </p>
  
  <p>To avoid any potential security issues, I flushed my iptable and allowed all on all ports for both nodes. They are also on the same virtual network.</p>
  
  <blockquote>
    <p>iptables -P INPUT ACCEPT</p>
  </blockquote>
  
  <p>When I start OpsCenter on either machine it sees both nodes but only has information on the node I am viewing OpsCenter on. It can tell if the other node is up/down, but I am not able to view any detailed information. It sometimes initially says 2 Agents Connected but after awhile it says 1 agent failed to connect. It keeps prompting me to install OpsCenter on the other node although it's already there.</p>
  
  <p>The OpsCenterd.log doesn't reveal much. There don't appear to be any errors but I see INFO: Nodes with agents that appear to no longer be running . </p>
  
  <p>I am not sure what else to check as everything but OpsCenter seems to be working fine.</p>
