Question: SSL routines:tls_post_process_client_hello:no shared cipher

[sertunc]

Hello, when i use this code block about TlsCipherSuite, i get this error "SSL routines:tls_post_process_client_hello:no shared cipher". can you give some advice?thank you.

public static KestrelServerOptions ListenVera(this KestrelServerOptions options, settings settings)
{
options.Listen(IPAddress.Parse(settings.ListenIP), settings.Port, listenOptions =>
{
listenOptions.UseConnectionLimits(veraSettings.ConnectionLimit);
listenOptions.UseHttps(adapterOptions =>
{
adapterOptions.OnAuthenticate = (context, authenticationOptions) =>
{
authenticationOptions.CipherSuitesPolicy = new CipherSuitesPolicy(new[]
{
TlsCipherSuite.TLS_DHE_RSA_WITH_AES_256_CBC_SHA256,
TlsCipherSuite.TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
});
};
adapterOptions.SslProtocols = SslProtocols.Tls12;
adapterOptions.CheckCertificateRevocation = false;
adapterOptions.HandshakeTimeout = TimeSpan.FromSeconds(veraSettings.TlsHandshakeTimeout);
adapterOptions.ClientCertificateMode = ClientCertificateMode.AllowCertificate;
adapterOptions.ServerCertificate =
new X509Certificate2(Path.Combine("certs", settings.ServerCertificateFilename),
veraSettings.ServerCertificatePassword);
adapterOptions.AllowAnyClientCertificate();
});
//listenOptions.UseConnectionLogging();
listenOptions.UseConnectionHandler();
});

        return options;
    }
