Failed to connect to the VMware lookup service

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  The certificate that was created on initial configuration is no longer valid.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:

  1. Login into vCenter VA Configuration https://%5Bhostname%5D:5480
  2. Select the Admin tab
  3. Click Toggle certificate setting, you will see Certificate regeneration enabled change to Yes.

During the bootup procedure you will see
