Does Kiwi syslog server support TLS 1.2? If so how to enable it?

I am trying to connect to kiwi syslog server in secure TCP mode. From my client side (c# code) I try to connect to kiwi syslog sever using TLS 1.2 protocol. But SSL Handshake from server is set to TLS 1.0

I installed kiwi server in Windows 7 SP1 and enabled TLS 1.2 in the system by modifying the system registry.

SSL handshakes captured using Network monitor are given below

Client HandShake

Server HandShake

Client side code( c#)

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

var tcpClient = new TcpClient(hostname, port);

var tcpClientStream = tcpClient.GetStream();

var sslStream = new SslStream(tcpClientStream, false, ValidateServerCertificate)

{

        ReadTimeout = timeout,

        WriteTimeout = timeout

};

sslStream.AuthenticateAsClient(hostname, new X509CertificateCollection(), System.Security.Authentication.SslProtocols.Tls12, false);
