[ovirt-users] VNC console connection fails [ovirt 4.5.3.1-1.el8]

Hello list, is there anybody else out there having problems to connect to a vm console via vnc or is it just me? We are running ovirt-engine 4.5.3.1-1.el8 on up to date ovirt-nodes. I can connect to every virtual machine by spice, but am unable to connect via vnc due to a tls handshake error. Remote-viever just shows "Failed to complete handshake Error in the pull function" (on windows and linux clients). Wireshark tls handshake capture looks supicious to me, server hello message is just 182 bytes long and doesn't coantain a server certificate. Is this normal? sincerely André
