vCenter Server – lookup service failed

Recently did a rack migration for which we had to shutdown SQL cluster and vCenter server including all Virtual machines.

After powering I was unable to login with my domain account and got the following error:

“Failed to connect to VMware Lookup Service. SSL certificate verification failed”


  • Login to vCenter server (SSH or RDP depending on vCenter server platform) and verified that the vmware-sso service is running.
  • Could not login with local admin@vsphere.local so logged into VA configuration https://:5480. ┬áVerified all services was running.
  • Verified SSO server and Active directory domain controllers time is not off by more than 5 minutes.
  • Found KB article on this error.


Found KB that provides information on this issue which seems to get triggered when you had change the IP or hostname of the vCenter server after its initial creation.

To fix the issue login to VA configuration: https://:5480.
Select admin tab
Check the “yes” radio button for “Certificate regeneration enabled:”
Click Submit.
Restart vCenter server
