You can use the improved feedback tool and the in-product feedback(IPF) in the vSphere Client to provide timely feedback to the VMware developers.
Here is an example of the in-product feedback window:
VMware vCenter Server 6.7.x
VMware vCenter Server 7.0.x
VMware vCenter Server 8.0.x
These feedback systems need to access "vcsa.vmware.com" and "feedback.esp.vmware.com" from vCenter and your browser when a user logs into the vSphere Client(HTML5).
This is expected behavior.
