IW 15.1.7 handlers randomic problem

[cprmlao@hotmail.com]

With IW 15.1.17

I have a handler, a Form using a Html TemplateForm  and a JS code used in document.ready().

I have in my app many handlers.

In the local network and with amazon EC2 I am using WIFI with my home router. I am not using  internet provider from mobile.

I am having randomic "404 error" with "resource not found" when using the app with the chrome browser in my mobile and Amazon EC2 Server.

Sometimes the Handler works, other times doesn´t work. When I tried debug I see it is trowing an error of  "404 - resource not found", randomically.


If I use the Chrome Desktop or my mobile with chrome  connected with IW server installed  in a PC  in the local network, there is no problem.

If I use the Chrome Desktop connected with IW server installed  in Amazon EC2 , I have no problem.

The  problem  only occur when  using chrome browser of my cell phone and  IW server in Amazon EC2.

I have noted that the problem happens when I use the crome browser of my mobile. If I use the default browser of my mobile there is no problem.
I have Android Oreo in the mobile and it is a recent Cell phone. So Chrome os updated in version 78.0.3904.62
What can be causing it?

//IW Handler

Code:

function TContentAgenda.Execute(aRequest: THttpRequest; aReply: THttpReply;
  const aPathname: string; aSession: TIWApplication;
  aParams: TStrings): boolean;
var
  jso,js:TJsonObject;
  ja:TjsonArray;
begin
  Result:=True;
  js:=TJSonObject.Create;
  ja:=TjsonArray.Create;
  try
    with Controller.DM.FDQQuery do begin
      Close;
      SQL.Clear;
      SQL.Add('Select A.* from TableTeste');
      .....
  js.AddPair('draw',TJSONString.Create(_draw));
      js.AddPair('recordsTotal',TJSONString.Create(....));
      js.AddPair('recordsFiltered',TJSONString.Create(....));
      js.AddPair('data',ja);
      wresult:=js.toJson;
Close;
  finally
    js.Free;
  end;
  aReply.WriteString(wresult);
end;

//JS code in html Template Form

Code:

<script>
  $(document).ready(function () {
    function listaAgenda() {
      let params = {
        data_inicial: moment().format('DD/MM/YYYY'),
        data_final: moment().add(1, 'days').format('DD/MM/YYYY'),
        med_ag: $('#IWUSU').val() || ''
      };
      //encodeURI
      $.ajax('/GetAgenda?' + encodeURI($.param(params)))
        .done(resp => {
          let out = JSON.parse(resp);
          let context = { qtde: out.recordsFiltered, items: out.data };
          context.hasItems = (parseInt(context.qtde, 10) > 0);
          let html = template_agenda_script(context);
          $("#id_agenda_menu").html(html);
        }).fail(erro => {
          alert(JSON.stringify(erro))
        })
    };
    listaAgenda()
  })
</script>
