We have this happening with an iPad mini 2 Wi-Fi (A1489) as well.Managed
student AppleID, DEP, supervised, and Config Profile for
Restrictions.Have been able to deliver update to iOS 11.0.1 while it is
locked, but disabling Lost Mode still fails.Also...
My JSS server time was off by 7 mins also, and fixing that solved the
"Problem contacting Apple services" error when attempting the upload of
our Apple DEP token to our JSS.
