Environment

VMware NSX
VMware vCenter Server

Cause

This issue occurs because the connection impacted at the Tier-0 (T0) Gateway, as the physical router (ACI) is not advertising the routes necessary to facilitate communication.

Resolution

Review the routing on the Tier-0 Gateway and ensure that the appropriate routing configurations are being advertised from the ACI (physical network) to allow traffic to reach the Aria Operations environment.
