Solution: This error occurs when the Cloudbreak instance is not authorized to use the role that you are trying to register as part of the Cloudbreak credential creation. The most common reason for this error is that when creating the CredentialRole AWS IAM role you did not provide the AWS ID. Refer to the Create CredentialRole documentation for correct steps.
