When I try to open a console to a vmware VM, I'm getting an error:
WebSock error: [object Event]
I can see that websockify script is running correctly
foreman 27571 0.0 0.0 156148 11932 ? S 16:06 0:00 /usr/bin/python /usr/share/foreman/extras/noVNC/websockify.py --daemon --idle-timeout=120 --timeout=120 5911 10.10.1.27:5956 --cert /var/lib/puppet/ssl/certs/foreman001.grid.prod.yyz.corp.pvt.pem --key /var/lib/puppet/ssl/private_keys/foreman001.grid.prod.yyz.corp.pvt.pem

I'm able to connect to the same IP:port with a VNC client, and a password I got from foreman, with no problems.
