网络同步不工作

websync在我的服务工作正常，但一些变化后，它停止工作，它不给我任何错误信息，一切似乎很好。但肯定有什么问题。我在我的网站上创建了测试页面，但没有在那里工作。我在这里张贴的代码，请看看和建议。

public partial class test : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Publisher publisher = new Publisher(new PublisherArgs() { RequestUrl = "http://www.ffrsdevserver.com/request.ashx" });          
            Data entity = new Data();
            entity.DeptID = 1.ToString();
            entity.StationId = "108";
            entity.Text = "UpdateAll";
            publisher.Publish(new Publication()
            {
                Channel = "/3db165bf2f25",
                DataJson = JSON.Serialize(entity)
            });
        }
    }
    [DataContract]
    public class Data
    {
        private string text = string.Empty;
        private string deptId = string.Empty;
        private string dataType = string.Empty;
        private string stationId = string.Empty;
        [DataMember(Name = "text")]
        public string Text
        {
            get { return text; }
            set { text = value; }
        }
        [DataMember(Name = "deptId")]
        public string DeptID
        {
            get { return deptId; }
            set { deptId = value; }
        }

        [DataMember(Name = "stationId")]
        public string StationId
        {
            get { return stationId; }
            set { stationId = value; }
        }
    }
