Environment

VMware vCenter Server Appliance 6.7.x

Cause

This issue occurs when deploying a vCenter Server Appliance 6.7 with an IP address that has no DNS record configured.  IP based deployments without DNS are not supported.

Resolution

Before deploying a vCenter Server Appliance 6.7 with a static IP address, verify that the IP address has a valid (internal) domain name system (DNS) registration.  

For more information about DNS requirements see: DNS Requirements for the vCenter Server Appliance and Platform Services Controller Appliance.
