FAQ

Is a Certificate Required for an HTTPS Listener?

If you use an HTTPS/TLS listener to forward traffic, you need to bind a server certificate to the listener for SSL handshake negotiations and server authentication.

If mutual authentication is required, you must bind a CA certificate to the listener to authenticate the certificate issuer.
