C# 使用证书、用户和密码调用 SOAP Web 服务

问：

我正在尝试调用一个旧的SOAP Web服务，该服务需要连接上的证书+用户和密码 这是我的尝试：

            X509Certificate2 cert = new X509Certificate2("cert.p12", "h/K3+7NpiY", X509KeyStorageFlags.Exportable);
            WSHttpBinding binding = new WSHttpBinding(SecurityMode.TransportWithMessageCredential);
            binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
            
            EndpointAddress endpointAddress = new System.ServiceModel.EndpointAddress("https:URL");

            SOAPClient1 client= new SOAPClient1(binding, endpointAddress);
            client.ClientCredentials.ClientCertificate.Certificate = cert;
            client.ClientCredentials.UserName.UserName = "user._.1";
            client.ClientCredentials.UserName.Password = "n6k5\">rvdR";
            client.ChannelFactory.Credentials.ClientCertificate.Certificate = cert;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11
                                                | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls13;

我得到了

{“身份验证失败，因为远程方发送了 TLS 警报：'176'。

证书是正确的，我通过soap-ui将它与凭据一起使用，一切正常。

我尝试了不同的绑定选项，但没有成功
