Android io.socket.SocketIOException:握手时出错

我正在使用Socket.Io开发一个Android应用程序。当我使用我的本地ip地址（192.168.1.22:4000）时，我从服务器获得了响应。但是当我使用域名（“）时，我得到了Io.Socket.SocketIOException:握手时出错异常我如何处理此问题。请检查下面的代码>提前感谢

                  JSONObject js = new JSONObject();
                  js.put("key",value);
                    js.put("key",value);

                socket = new SocketIO();
         socket = new SocketIO("http://mydomain.com:80"); 


            socket.addHeader("id", 20);


        socket.connect(new IOCallback()
        {

            @Override
            public void onMessage(JSONObject json, IOAcknowledge ack)
            {
                // TODO Auto-generated method stub
                  System.out.println(".....onMessage.......");
            }

            @Override
            public void onMessage(String data, IOAcknowledge ack)
            {
                // TODO Auto-generated method stub
                  System.out.println(".....onMessage... STR....");
            }

            @Override
            public void onError(SocketIOException socketIOException)
            {
                // TODO Auto-generated method stub


            }

            @Override
            public void onDisconnect()
            {
                // TODO Auto-generated method stub

            }

            @Override
            public void onConnect()
            {
                // TODO Auto-generated method stub
                System.out.println("....connected ....");
             }

            @Override
    public void on(String event, IOAcknowledge ack, Object... args)
            {
                // TODO Auto-generated method stub

                Object[] arguments = args;
                JSONObject jsb = (JSONObject) arguments[0];


                    } catch (JSONException e)
                    {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }

            }

        },js,"event name");
    } catch (MalformedURLException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

这个问题没有解决办法吗？
