1. When you add a VMware Cloud Director host, Veeam ONE saves to the configuration database a thumbprint of the TLS certificate installed on the VMware Cloud Director host and all vCenter servers under it. During every subsequent connection to the server, Veeam ONE uses the saved thumbprint to verify the server identity and avoid the man-in-the-middle attack.

   If the certificate installed on the server is not trusted, Veeam ONE displays a warning.

   - To view detailed information about the certificate, click **View Certificate**.
   - If you trust the server, click **Trust and Continue**.
   - If you do not trust the server, click **Cancel**. Veeam ONE will display an error message, and you will not be able to connect to the server.
