Teradici Console cannot discover devices

I have a EVGA PCoIP zero client being used with Horizon View 5.3.

Using the zero client, I am able to connect to a provisioned VM.

Using the vSphere client, I deployed the Teradici PCoIP mgt OVF and configured the networking.

I then launched the Teardici PCoIP Mgt Console via Firefox.

When I go to the devices screen, I do not see the zero client.

I tried adding a range of IPs and the FQDN but still no luck adding the device.

Do I need to enable something in order to add devices?

I would like flash the current device with a new firmware update.

thanks
