After upgrading the service instance, rendering the dashboard returns Access Denied error through Application Manager -> Services -> Manage.
The dashboard URL and the Spring Cloud Service backend app route should be the same. In this case, they were different. Thus, the Access Denied error.
The dashboard URL is returned by the SCS broker and stored is the Cloud Controller database when the service instance is upgraded. It's possible that the SCS broker is in a bad state, and returned an invalid dashboard url.
Please follow the steps below to update the dashboard URL
