• In the Omnissa Horizon dashboard, "Invalid Certificate Detected" message is seen

Environment

When vCenter certificates are replaced, Horizon does not trust the new vCenter certificate

Resolution

1. When Horizon Console displays an Invalid Certificate Detected dialog box, click View Certificate.
2. Examine the certificate thumbprint in the Certificate Information window.
3. Examine the certificate thumbprint that was configured for the vCenter Server. See Managing Certificates Using the vSphere Client and vCert - expired certificate replacement script for details.
4. Verify that the thumbprint in the Certificate Information window matches the thumbprint for the vCenter Server.
5. Determine whether to accept the certificate thumbprint.

Option	Description
The thumbprints match	Click Accept to use the default certificate.
The thumbprints do not match	Click Reject. Troubleshoot the mismatched certificates. For example, you might have provided an incorrect IP address for vCenter Server.
