Looks like websocket is being initialised twice, then failing the second time?
Gets around the usual port checking by getting a free port, then failing.

WebSocket server settings:
  - Listen on localhost:56703
  - Web server. Web root: /opt/noVNC
  - No SSL/TLS support (no cert file)
  - proxying from localhost:56703 to :66424
  - Navigate to http://localhost:56703 in web browser to connect
  - Press 'Ctrl + C' to close connection ( Note: VDT instance not persistent )

Could do with a higher level 'retry' loop.
