Any chance the "Use Secure WSS" is checked in sunstone config? Can you check/uncheck and retry with it unchecked just in case?

Secure WSS wasn't checked, but I tried to check/uncheck and run once again with unchecked - nothing changed :-(

Otherwise, kill your sunstone proxy and restart it manually:

python /usr/share/opennebula/websockify/websocketproxy.py --target-config=/var/lib/one/sunstone_vnc_tokens 29876

Here seems to be an issue - if websockify process runs in time of sunstone is starting - python process is defunct. If a defunct python proces exist in system, VNC server is disconnected immediately and 10 lines is added to websockify console:

and see if it says something interesting to the console when you are trying to connect to the VM.
