Can't seem to verify new host with vsphere web client

[ejacobs]

Trying to install Hotlink's Hybrid Express. Last step is to add their EC2 agent vm as a host. It works up to a point but ends up saying that it cannot verify the SSL cert. I've tried going into Vsphere web client going to manage vcenter and edit settings. It sees the host I'm trying to add and gives me a checkbox to verify it. I click, but it doesn't seem to take

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:

1. Run services.msc and stop the VMware vSphere Web Client service.
2. Go to the %ProgramData%\VMware\vSphere Web Client\SerenityDB\ directory.
3. Create a backup of the file *VcDirectory.
   
   Note: This file does not have a file extension.
   
   
4. Delete the *VcDirectory file.
5. Start the vSphere Web Client service.

Hope this helped

Best regards
