Issue/Introduction
vSphere Client -> Hosts and Clusters -> Host -> Configure ->System -> Certificate will display blank page instead of showing the host certificate details.
The host Client will display the host certificate successfully.
Environment
VMware vSphere ESXi
Cause
ESXi Certificate Mode is set to "thumbprint" instead of default "VMCA" on vCenter.
Resolution
The vpxd.certmgmt.mode is located in the advanced settings of the vCenter, and can be edited with the steps below:
1. In the vSphere Client, navigate to the vCenter Server instance.
2. Select the Configure tab.
3. Select Advanced Settings.
4. Click Edit Settings.
5. In the Name field, type a name for the setting, in this situation it is: vpxd.certmgmt.mode
6. Edit the setting to either "vmca" or "custom" depending on your environment.
7. Restart the vCenter services after saving the change
service-control --stop --all && service-control --start --all
Important: If the ESXi hosts use custom CA signed certificates, enabling vmca mode and renewing will overwrite the custom certificates. Please use caution before choosing the proper path.
