Resolution

 

• In the above scenario, the vCenter's SSL Certificates were replaced post which the issue had occurred.

• Edit the above Compute Manager via the Edit button and update the correct thumbprint and click on Save.
• The thumbprint can be retrieved by using the following command : openssl x509 -in /etc/vmware-vpx/ssl/rui.crt -fingerprint -sha256 -noout
• Post that, the Compute Manager's status showed up as "Up" and the newly created segment was visible on the vCenter's Network Inventory.
