The app tries to connect to the Apple APNs server. The expected server response time is 5 seconds or less.
If the app notifies you that the APNs server could be reached, the device is able to receive commands from Sophos Mobile Control server through APNs.
If the app notifies you that the APNs server could not be reached, your network does not allow APNs communication and thus Sophos Mobile Control is not able to manage iOS devices. To correct this, make sure that the requirements described in Requirements are met.
