Otherwise, you will not be able to import the TLS certificate. - If a PFX file contains a certificate chain, only the end entity certificate will be imported. ::: To import a TLS certificate from a PFX file, do the following on the machine where Veeam ONE server component is installed: 1. Run the Veeam ONE Settings utility. For more information, see [Veeam ONE Settings Utility](appendix.md). 2. In the **Server** section, open the **Web API Certificate** tab. 3. To import the certificate, click **Import** and browse the certificate file.
