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.

The noVNC browser client works just fine, but for some reason the default download to remote-viewer fails on the same hosts. All the end-user gets is a quick flash of the remote-viewer window on their screen.
