Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown

I'm trying to query a list from an intranet SharePoint site using the following code:

                BasicHttpBinding MyHttpBinding = new BasicHttpBinding();
                MyHttpBinding.Security.Mode = BasicHttpSecurityMode.Transport;
                MyHttpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
                MyHttpBinding.MaxReceivedMessageSize = 50000000;
                MyHttpBinding.ReaderQuotas.MaxArrayLength = 50000000;
                MyHttpBinding.ReaderQuotas.MaxStringContentLength = 50000000;
                MyHttpBinding.ReaderQuotas.MaxNameTableCharCount = 50000000;
                MyHttpBinding.ReaderQuotas.MaxDepth = 50000000;
                MyHttpBinding.AllowCookies = true;
                
                EndpointAddress ICCProjectsAddress = new EndpointAddress (new Uri(https://mysite/sites/bcssoc/ic/pm/Lists/SOC%20Projects/_vti_bin/lists.asmx));
                ListsSoapClient ICCProjectsClient = new ListsSoapClient();

                ICCProjectsClient.Endpoint.Address = ICCProjectsAddress;
                ICCProjectsClient.Endpoint.Binding = MyHttpBinding;

                var xml = await ICCProjectsClient.GetListItemsAsync("SOC%20Projects", null, null, null, null, null, null);

                StatusText.Text = xml.ToString();

But when it tries to GetListItemsAsync it returns the following error:

{System.ServiceModel.FaultException: Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.

I've looked just about everywhere on the web, but there is nothing that helps with Win8Apps, everything is for desktop apps and Win8 doesn't have the same functions.
