While connecting to Web client I got following message.
“Failed to connect to VMware Lookup Service. SSL certificate verification failed.”
Post investigation I remembered that I changed the host name so need to regenerate the certificates
Following procedure was followed to resolve it
Access the admin console for VCSAhttps:// or fqdn>:5480
Navigate to Admin Tab
Click “Toggle certificate setting” under “Actions”
Restart the vCenter Server Appliance
During the restart certificates will be regenerated
Ensure we roll back the Toggle certificate setting under Admin Tab
