Problems connecting to SAP with sapnco

Question

I am trying to connect to SAP with a little c# program using SAPNCO x64 v. 3.0.2 with this code:

public partial class Connection
{
    public class Configuration : IDestinationConfiguration
    {
        public event RfcDestinationManager.ConfigurationChangeHandler ConfigurationChanged;

        public bool ChangeEventsSupported()
        {
            return false;
        }

        public RfcConfigParameters GetParameters(string destinationName)
        {
            var Parameters = new RfcConfigParameters();
            if (destinationName == "TEST")
            {
                Parameters.Add(RfcConfigParameters.AppServerHost, "...");
                Parameters.Add(RfcConfigParameters.SystemID, "...");
                Parameters.Add(RfcConfigParameters.SystemNumber, "01");
                Parameters.Add(RfcConfigParameters.LogonGroup, "COMMON");
                Parameters.Add(RfcConfigParameters.User, "...");
                Parameters.Add(RfcConfigParameters.Password, "...");
                Parameters.Add(RfcConfigParameters.Client, "...");
                Parameters.Add(RfcConfigParameters.Language, "EN");
                Parameters.Add(RfcConfigParameters.PoolSize, "5");
                Parameters.Add(RfcConfigParameters.MaxPoolSize, "10");
            }
            else
                throw new ArgumentException();

            return Parameters;
        }
    }

    public void ConnectionTest()
    {
        RfcDestinationManager.RegisterDestinationConfiguration(new Configuration());
        RfcDestination destination = RfcDestinationManager.GetDestination("TEST");
        destination.Ping();
    }
}

When I call Ping() I get this error:

LOCATION SAP-Gateway on host ... / ...

ERROR Gateway not connected to local R/3

I can figure it out. Any would be appreciated. Thanx.

NB: I have replaced sensible data with dots, of course.

Answer 1

I have solved the problem replacing this line:

Parameters.Add(RfcConfigParameters.AppServerHost, SAPServeHost);

with this one:

Parameters.Add(RfcConfigParameters.MessageServerHost, SAPServeHost);

it was just a wrong configuration.
