An error occurred loading data. Request failed with status code 403

I’m getting below error in sonar type while accessing Roles and SSL certificates and Realm options in UI.

An error occurred loading data. Request failed with status code 403.

In Log we got below message

*UNKNOWN org.sonatype.nexus.siesta.internal.AuthorizationExceptionMapper - (ID 2bd48f7d-cdbf-49da-b7e5-08df5524c165) Response: [403] (no entity/body); mapped from: org.apache.shiro.authz.UnauthenticatedException: This subject is anonymous - it does not have any identifying principals and authorization operations require an identity to check against. A Subject instance will acquire these identifying principals automatically after a successful login is performed be executing org.apache.shiro.subject.Subject.login(AuthenticationToken) or when ‘Remember Me’ functionalityis enabled by the SecurityManager. This exception can also occur when a previously logged-in Subject has logged out which makes it anonymous again. Because an identity is currently not known due to any of these conditions, authorization is denied.
