If your Nutanix environment is using the default self-signed SSL certificate, replace it with a certificate that is signed by a CA. The installation program requires a valid CA-signed certificate to access to the Prism Central API. For more information about replacing the self-signed certificate, see the Nutanix AOS Security Guide.

If this certificate are from a private PKI then additional steps for a User PKI has to be setup prior to installation, please follow the Configuring a custom PKI for further information: https://docs.openshift.com/container-platform/4.13/networking/configuring-a-custom-pki.html
