Error: "Failed to unregister vCenter Server 'vcenter-name'. Hosts from this vCenter Server are still referenced" when unregistering vCenter from VCD

Products

• VMware Cloud Director

Issue/Introduction

• Unable to Unregister a vCenter Server from VMware Cloud Director (VCD)
• When trying to Unregister a vCenter Server from VCD, the following error is displayed:
  
  [ ########-####-####-####-############ ] Failed to unregister vCenter Server "<vcenter-name>". Hosts from this vCenter Server are still referenced. Here are the first 1 out of 1: [<esxi-name>].

• This prevents successful removal of the vCenter from VMware Cloud Director.

Environment

• VMware Cloud Director 10.x

Cause

This issue occurs when the ESXi host is removed directly from vCenter before it is properly unregistered or deleted from within VMware Cloud Director. As a result, VCD retains residual references to associated resources.
