Hello,
Well a quick check of the hosts say that they have ovirt-
vmconsole enabled on their firewall, but there doesn't seem to be any
logs for the vmconsoles on them. Running wireshark on one of the end-
user machines shows that the host does send packets back and forth but
then the end-user machine TCP resets the connection. (I assume due to
the credential failure.) So it doesn't seem to be a firewall issue.
Is there anything I can do to get some more logs from the vmconsoles on
the Host?
Thanks.

Hello Patrick,
with noVNC the connection is made via the
websocket-poxy service (probably on the engine server).
The remote-viewer connects directly from the client machine to the
virtual host the VM is running on. Maybe check the network/firewall
between the client and the host, also the OTP expires after 120
seconds.

Paul S.

The most common problem is the CA of oVirt not trusted in the web
