have been re-building my lab yesterday with all the latest vCloud suite 5.1 GA bits.
After deploying and configuring the vCenter Virtual Appliance, when I was trying to login to the vSphere web client, I kept receiving the error “ Failed to connect to VMware Lookup Service https://[hostname]:7444/lookupservice/sdk – SSL certificate verification failed. ” and could not login.
This issue occurs if you have changed the hostname or IP address of the vCenter Virtual Appliance. The certificate that was created on initial configuration is no longer valid. To resolve this issue, follow the steps below:
Login into vCenter VA Configuration https://[hostname]:5480
Select the Admin tab
Click Toggle certificate setting, you will see Certificate regeneration enabled change to Yes.
Re-boot the Virtual Appliance
During the bootup procedure you will see
Hostname or IP has changed. Regenerating self signed certificate.
