We've signed up with Apple DEP and successfully put a token into the JSS. Inside the JSS, we can see the two test OS X machines we've added to DEP and their requisite serial numbers.
When we go to re-image one, the DEP dialog that our institution has been detected shows up, but when you hit continue, the computer cannot contact the MDM server with the error "Failed to contact Mobile Device Management server. Your Mac will not be configured with default settings from Institution Name. To apply these settings later, click Continue." Which seems odd, because inside the JSS, the MDM server is clearly contacting the DEP to show us the machines that have been added.
We do not currently have port 8443 open incoming outside our intranet for this server, as it is in development. I was wondering if that could be the issue -- and perhaps the JSS can contact DEP when I'm logged into it because it's establishing an outgoing connection, not an incoming one? Basically, I'd like to understand what's happening after the computer knows it is associated with our institution (which it does, as it has our DEP e-mail and phone number) without just opening the required ports in the documentation.
Does anyone know?
