[Openstack] Dashboard VNC Console failed to connect to server

Hey Tony,

Slightly related - I'm getting a valid link form the dashboard that gets to VNCProxy and such, but the page that comes active reports a "Server timeout". Any idea how to diagnose this and what's happened/not responded?

http://172.17.1.50:6080/vnc_auto.html?token=f96cf65b-1a2f-415c-97f7-90da7cdc102a&title=zerglet(b13812ac-8310-49ea-97e6-50ff062754af)

In the javascript console, here's what I'm seeing:

New state 'loaded', was 'disconnected'. Msg: noVNC ready: native WebSockets, createImageData rendering
util.js:71New state 'connect', was 'loaded'.
util.js:71New state 'ProtocolVersion', was 'connect'. Msg: Starting VNC handshake
util.js:72New state 'failed', was 'ProtocolVersion'. Msg: Failed to connect to server
util.js:71New state 'failed', was 'failed'.


Any ideas?

-joe
