Unable to register due to error (HTTP Status 500)

I’ve been trying to get our latest Xibo CMS (2.02) to register a new Xibo box in the CMS but it keeps reporting on the client box an Error 500 message. We captured a dump of the communication between the two devices in a hope someone could provide some insight as to where the issue may exist:

Thanks
Andre
