• Running dig on the NSX Manager shows the correct output including a lowercase DNS name: /usr/bin/dig <fqdn>
• The hostname for vCenter was previously in uppercase and has been manually changed from the vCenter console instead of following the proper procedure with the VAMI

 

Cause

The case of the vCenter PNID does not match DNS.

Resolution

1. Take an offline snapshot of the vCenter and VCF Installer / SDDC Manager.
2. Update the PNID using the vCenter VAMI which will generate a new machine certficate.
3. Update the deployment spec to use the newly generated thumbprint for vCenter 
4. Update the vCenter known host on VCF Installer or SDDC Manager.
5. If the VMCA certificate has changed then sync VCF Installer / SDDC Manager with the vCenter trust store.
6. Retry the workflow from VCF Installer.
