Apple Configurator Supervising devices Error
I am new to iOS and Supervision so please bear with me. I tried setting up the Configurator but when I try to prepare it I get an error at the Download Activation Record, it says it failed. The only other additional information it gives me is:
Description: unsupported URL Code: -1002 Domain: NSURLErrorDomain
Description: unsupported URL Code: -1002 Domain: kCFErrorDomainC...
I have several iOS device that need to be supervised and I am not sure what the issue is. Any Ideas?
Mac mini (Late 2014), OS X Yosemite (10.10.4)
