var handler = new HttpClientHandler();

                    handler.SslProtocols = SslProtocols.Tls | SslProtocols.Tls11 | SslProtocols.Tls12;
                    handler.ServerCertificateCustomValidationCallback = delegate { return true; };

                
var httpClient= new HttpClient(handler);

// wrap this in config

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
                ServicePointManager.ServerCertificateValidationCallback +=
                    (sender, cert, chain, sslPolicyErrors) => true;
