title: novnc:something went wrong,connection is closed
body: <p>I can't connect my vm with novnc.</p>
  
  <p>I am playing openstack with two nodes. Now I create a vm and I want to connect it with novnc. I use the command <code>nova --os-region-name=RegionOne get-vnc-console vm1 novnc</code> to get the VM1 novnc url. And I use it at the firefox.
  But it shows that <code>something went wrong,connection is closed</code>:</p>
