[one-users] VNC proxy is working but Sustone VNC window does show error

Just in case, my configuration:
10.2.2.2 - KVM host with VMs
10.18.1.7 - only OpenNebula and Sunstone front-end

* Can you connect directly without no VNC to those VMs (10.2.2.2:5916 for example) with a standard vnc client

Yes, with no problem

If I start proxy manualy "/srv/cloud/one/share/noVNC/utils/websockify 35792 10.2.2.2:5916", I can't connetct from VNC client to 10.18.1.7:35792, it shows me "ignoring socket not ready":

root at ubuntu:/srv/cloud/one/share/noVNC/utils#  /srv/cloud/one/share/noVNC/utils/websockify 35792 10.2.2.2:5916
WARNING: no 'numpy' module, HyBi protocol is slower or disabled
WebSocket server settings:
  - Listen on :35792
  - Flash security policy server
  - No SSL/TLS support (no cert file)
  - proxying from :35792 to 10.2.2.2:5916

  1: 10.2.0.3: ignoring socket not ready
  2: 10.2.0.3: ignoring socket not ready

I found that I can connect to 10.18.1.7: 35792 from browser (http://10.18.1.7:6080/vnc.html) when I start both launch.sh script and also websockify 35792 10.2.2.2:5916
