Use firefox's developer console to see what the problem is. It could be:
- web socket not available outside (use proxy that supports websockets
or make helper app listen on outside interface)
- sunstone running in https connection and trying to load non-secure web
socket (change wss = only in config)
- self signed certificate (add CA to browser or paste link from console
in browser (with port like 29876) and accept certificate also there)
or a combination.

You need to forward web sockets or reconfigure (I think I've seen such
option somewhere) noVNC to emulate WebSockets in http requests or just
allow websocketproxy.py to listen on outside interface. I've chosen the
last option.
