Cause

The error is usually seen because the account doesn't have the necessary permissions to perform all the task.  In this case the permissions for Customer Managed Keys (CMK) are not set correctly. The volume being restore was using custom CMK, and the IAM role attached to CloudPoint host should be added as one of the users of the custom CMK.

Solution

Review the IAM role assigned to CloudPoint for any permission issues.
For a list of permission refer to CloudPoint Administrator Guide:
