On the main dashboard, you may see only “Isolated Devices” and “No Connectivity” instead of the expected interconnection map. This can occur even if your RN150 has successfully discovered devices and collected details such as processes, hardware, and operating systems (visible in Dashboard > Assets > Licensing), and you can view server connections in Dashboard > All Applications.

This behavior occurs when application stacks are not defined. RN150 requires Application Stacks to group related assets and visualize dependencies. Without them, servers appear as isolated nodes with no connectivity.
