Configuring TLS Authentication of Server to Agents and Users
This is the second highest level of TLS security and requires that you provide a server certificate for the Server that is signed through a chain to a trusted root CA. You must also provide the certificate of the CA (Certificate Authority) that signed the Server's server certificate. If you are not working in a production environment, you can also use a self-signed server certificate.
If the Server's server certificate or the associated CA certificate is missing or expired, the Agents do not allow communications with the Server.
