Device does not contact MDM

We have a device which does not communicate with our MDM server. When we checked the console logs we found that device receives the push notification but does not respond to MDM server. When a restart is performed, it again communicates. From time to time it stops working and we have to restart to bring back communication.

Feedback has been raised with sysdiagnose - FB12062214

Any help would be appreciated.
