Windows 10 2004 Release or lower? NT Kernel should support TLS 1.3.

Fixed already. I changed target framework to 4.8 and set SslProtocols here: click to public SslProtocols SslProtocols { get; set; } = SslProtocols.Tls | SslProtocols.Tls11 | SslProtocols.Tls12 | SslProtocols.Tls13;

Then go to click and changed to sslStream.AuthenticateAsClient(address.Host, new X509CertificateCollection(), SslProtocols, true);

also I changed from click to ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls13;

After all this I recompiled the Leaf library and it works fine!
