[ovirt-users] noVNC not working

Hello: I upgraded my engine manager (ovirt-engine-3.5.0.1-1.el6.noarch) at the weekend and noVNC is no longer working :( The error I am getting is: Failed to connect to server (code: 1006) have attempted to downgrade noVNC (novnc-0.4-7.el6.noarch) but it still down not work. CA.crt has been imported again and am using a commercial SSL certificate. Any ideas please ? Thanks, Phil
