C# Application connecting SAP PI over https

Hi,

I'm developing a console .NET client application to connect to our partner's remote server SAP PI over a https channel. Unfortunately we've faced many problems and I'm not sure what more to do. I will try explain as best as I can and if someone could help me I'd be very grateful!

The remote server using SAP PI has the fictitious URL:

https://dev.servereai30.server.com/XISOAPAdapter/MessageServlet?channel=B2B_MYENTERPRISE:PROJECT:SOAP_SND_MYENTERPRISE_Sellout

When I access the URL, providing user and password given by our partners, the server seems to respond correctly:

I've received the wsdl from my partner and I've started developing a C# application to connect to Web Service. After loading wsdl as a Service Reference this is the app.config created by Visual Studio.

<?xml version="1.0"?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">

        </sectionGroup>
    </configSections>
    <startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="Sellout_OBBinding">
                    <security mode="Transport">
                        <transport clientCredentialType="Basic"  />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
                <binding name="Sellout_OBBinding1" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://dev.servereai30.server.com/XISOAPAdapter/MessageServlet?channel=B2B_MYENTERPRISE:PROJECT:SOAP_SND_MYENTERPRISE_Sellout"
                binding="basicHttpBinding" bindingConfiguration="Sellout_OBBinding"
                contract="SellOutWSDL.Sellout_OB" name="Sellout_OBPort" />
        </client>
    </system.serviceModel>
</configuration>


And this is a sample application code:

var wsRefa = new Sellout_OBClient();
wsRefa.ClientCredentials.UserName.UserName = "<user>";
wsRefa.ClientCredentials.UserName.Password = "<password>";
wsRefa.Sellout_OB();

The application breaks with the message: Could not establish secure channel for SSL/TLS with authority 'dev.servereai30.server.com'. I thought the problem was that the server certificate wasn't being accepted by the client machine, but I revised the certificate channel and everything seems fine.

The Stack Trace:

Does someone have an idea how solve this problem?
