When connecting to a vCenter Server Appliance using the Web Client this error is shown:

Failed to connect to VMware Lookup Servicehttps://vCVA_IP_address:7444/lookupservice/sdk – SSL certificate verification failed.

To resolve this issue, toggle the certificate settings.

  1. Log in to the vCenter Server Appliance Web interface at https://hostname:5480/.
  2. Click the Admin tab.

    • vCenter Server 5.5: Select Yes under Certificate regeneration enabled.
  4. Click Submit.
  5. Reboot the vCenter Server Appliance.
