vROps cert thumbprint and trust issue

After renewing certificate for one on my vCenters and refreshing connection with vROps, I was not able to re-connect NSX appliance.

The error messages was:

javax.net.ssl.SSLHandshakeException: com.vmware.vim.vmomi.client.exception.VlsiCertificateException: Server certificate chain is not trusted and thumbprint doesn’t match

Here is my playbook to fix the issue:

  1. In vROps navigate to Administration->Management->Certificate
  1. Find and delete the old vCenter certificate that vROps was using for the vCenter adapter instance in question.
  2. Stop the adapter instance from the cloud accounts page (check which collector the adapter is running on from the cloud accounts page)
  1. SSH to the collector where the instance is running and restart the collector service with the command “service vmware-vcops restart collector
  2. After 10 minutes, start the adapter instance for vCenter and test the connection
