If a device is
registered between backup and failure events, SAP Mobile Server has no
registration information for that device after recovery.
- Validate the
issue by checking SAP Mobile Server logs for this message:
Invalid or Expired User Name and/or Authentication
Code.
This message shows that an unregistered device has tried to connect. No message is
sent or received between this device and SAP Mobile Server.
- Resolve the issue by asking the device user to reregister the application
connection.
