Environment

VMware NSX

Cause

The NSX Manager VIP certificate SAN field was incorrectly configured, using the NSX manager node name instead of the correct VIP name.
This incorrect SAN field caused authentication and communication failures between SDDC Manager and NSX-T Manager during audit verification, leading to precheck failure.

Resolution

Make sure the NSX Manager VIP certificate SAN field with the correct VIP name. Instead of the individual node name.
