I get error 3194 with Apple Configurator when trying to prepare my ipad

Hi,

I am testing out Apple Configurator 1.4.2 (iTunes is up to date, as is Mac OS, at 10.8) for deploying profiles to an upcoming iPad fleet. I have run into two issues:

- With an iPad2 running iOS7, and the "Supervision" option set to "ON", the Configurator downloaded iOS 6.1.3 successfully and tried to apply it, failing with the error 3194

- With an iPad2 running iOS6.1.3 with the same options as above, it failed also with error 3194 and bricked the iPad. Restore also fails

Does anyone know what is causing the error 3194? I have run through Google and all it says is that the system cannot contact the Apple Server, but if I downloaded the updates successfully this can't be the issue, can it?
