Failed to connect to VMware Lookup Service, SSL certificate verification failed

Recently I have been playing in my lab with VCSA and vCNS, I found that when I tried to connect to the vCenter I received this error:

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

I was stuck for a little while as to why I was getting this error, then I noticed that the SSL Cert had a different name to the appliance due to it being deployed and then renamed. Lucky for me the fix for this is very simple!

  • Go to http://:5480
  • Click the “Admin” tab
  • Change “Certificate regeneration enalbed” to yes, this is either done with a toggle button to the right or radio button depending on the VCSA Version.
  • Restart the vCenter Appliance
  • Once the Appliance reboots it will re-generate the certificates
  • Change “Certificate regeneration enalbed” to no, this is either done with a toggle button to the right or radio button depending on the VCSA Version.

try to reconnect your appliance / application to vCenter and it should work no problems.
