To resolve this issue, remove the file containing left-over SSL thumbprint file, so that the vSphere Web Client is forced to use the new SSL Thumbprint.
To remove the file containing left-over SSL thumbprint file:
- Run services.msc and stop the VMware vSphere Web Client service.
- Go to the %ProgramData%\VMware\vSphere Web Client\SerenityDB\ directory.
- Create a backup of the file *VcDirectory.
Note: This file does not have a file extension. - Delete the *VcDirectory file.
- Start the vSphere Web Client service.
Hope this helped
Best regards
