Hi, 

Thank you for bringing this to our attention! We’re aware that the Administration Hub Diagram page can have limitations when displaying connections in environments with a larger number of servers, which is often related to node card and connection rendering constraints.

By default, the diagram shows Server-level connections, and when you click on a database or application, it displays the Application-level connections related to that databse/applciation. So the second behavior you described is expected.

To help us improve this feature, could you please share the number of Application Servers in your environment? We’ll use this information to simulate similar scenarios during development and work on optimizing the diagram page.

We appreciate your feedback and support!
