unable to add controller/vserver in snapcreator config - sc version 4.3.0P3

I am trying to create a config in scnapcreator server but unable to add Vserver. Getting below error.

Operation failed, Check GUI logs for details. ( STORAGE-02152 STORAGE-03101: Determining Clustered ONTAP identity for [10.131.255.42] failed with error [netapp.manage.NaAuthenticationException: Authorization failed]. )

maybe double-check the user name and password, as it showed "authorization failed"?
