Issue when invoking SOAP WCF web service from plugin Dynamics CRM 365

Hello

I get this message bellow infrequently when I invoke web service in crm plugin after creating or updating record.

Unexpected exception from plug-in (Execute): System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'

this is my web server binding configuration

<bindings>
        <basicHttpsBinding>
            <binding>
                <security mode="Transport">
                    <transport clientCredentialType="Windows">
                        <extendedProtectionPolicy policyEnforcement="Always"></extendedProtectionPolicy>
                    </transport>
        <message clientCredentialType="UserName"/>
                </security>
            </binding>
        </basicHttpsBinding>
    </bindings>

And I called it from plugin :

BasicHttpsBinding binding = new BasicHttpsBinding();
binding.Name = "BasicHttpsBinding_IServiceIntegration";
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;

binding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Windows;
binding.Security.Mode = BasicHttpsSecurityMode.Transport;

EndpointAddress myEndpoint = new EndpointAddress("https://myurlwebservice/ServiceIntegration.svc");
ServiceClient = new ServiceIntegrationClient(binding, myEndpoint);

ServiceClient.ClientCredentials.Windows.ClientCredential.Domain = "domain";
ServiceClient.ClientCredentials.Windows.ClientCredential.UserName = "user name";
ServiceClient.ClientCredentials.Windows.ClientCredential.Password = "password";

The IIS server configuration

    you are setting basicHttpsBinding/clientCredentialType="UserName" and binding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Windows;
    basic authentication and windows authentication are two different things.
