Description
Apple devices enrolled in MDM fail to receive configuration profiles or app installs.
Symptoms
Devices show as enrolled but no apps or settings apply.
Profiles stall or fail with timeout errors.
Root Cause
Push certificates may have expired, or APNs connectivity is blocked by firewalls.
Resolution Steps
Check if the Apple Push Certificate has expired in the MDM console.
Renew and re-upload the certificate to the MDM platform.
Verify that ports 2195–2196 and 5223 are open to Apple servers.
Reboot the device and force sync from the console.
Check for duplicate or conflicting device entries.
Follow-up
Re-enroll the device if problems persist.
Schedule certificate renewals proactively.
