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

I’m currently halfway through following the excellent CBTNugggets course: VMware vSphere 5.5 VCP5-DCV by Keith Barker.

I have my vSphere lab set up and configured and came across this error when trying to login to vCenter:

LoginError

I figured out that the reason was to do with me changing the hostname of the vCenter appliance which broke the self-signed certificate that was created when I first installed the appliance.  If you change the IP address then you will also get this error.

The Solution:

The solution turned out to be quite simple:

  1. Log in to the vCenter appliance and select the Admin tab.
  2. Select the ‘Yes’ radio button where it says:”Certificate regeneration enabled’ followed by the submit button. (As per the screenshot below)

  3. Reboot the appliance.
  4. On rebooting the appliance, I noticed the following message on the console:
    onBootAfterTheFix

This was all that I needed to do and I was then able to log back in to vCenter and continue my studies.
