C # WCF - Failed to call service

Question

I get the following error when trying to use the WCF test client to access my new web service. What is strange, every time after a while it will be executed, and then this error will start popping up.

Failed to call the service. Possible reasons: the service is unavailable or unavailable; client side configuration does not match proxy; existing proxy is invalid. See stack trace for more details. You can try to restore by starting a new proxy server, restoring the default configuration, or updating the service.

My code (interface):

[ServiceContract(Namespace = "http://rivworks.com/Services/2010/04/19")]
public interface ISync
{
    [OperationContract]
    bool Execute(long ClientID);
}

My code (class):

public class Sync : ISync
{
    #region ISync Members
    bool ISync.Execute(long ClientID)
    {
        return model.Product(ClientID);
    }
    #endregion
}

My config (EDIT - hosted the entire section of the Model service):

2 questions:

• What am I missing that causes this error?
• How to increase the waiting time for the service?

TIA!
