Mobile IOS Iphone 8 plus and Iphone 12 pro max are not getting identified

Team ID , Certificates have been uploaded but the Provisioning devices are not able to identify the Iphones.
Manage Agents> Devices section display the iphone 8 + or Iphone 12 pro max in the entry correctly.
Both 8plus and 12 pro max are getting identified with a green tick mark under Provisioning Profile > Provisioning devices section but as i click on Ok button the below error appears like Couldn’t finalize upload “Provisioning Profile” Unable to sign appears.

Please help to add this device in testproject under account IOS.

It is fixed now. Tried generating those certificates again and after uploading again, they have worked.
