Solution Verified - Updated -


  • I want to access openstack instances vnc console using SSL/TLS
  • Suddenly access to consoles stops working
  • I get the following error when I manually execute nova-vnc-proxy in debug mode

     30: handler exception: WSRequestHandler instance has no attribute 'last_code'
     30: Traceback (most recent call last):

        self.client = self.do_handshake(startsock, address)
      File "/usr/lib/python2.7/site-packages/websockify/", line 628, in do_handshake
        if wsh.last_code == 101:
    AttributeError: WSRequestHandler instance has no attribute 'last_code'
