I'm using the following code to make cross domain request using $.getJSON, request completed but with errors, I cannot exactly detect what is the thrown error.

Based on callback param of request value I route it to a certain method which retrieves required JSON data.

$.getJSON("http://wthsrvr:45452/Handler.ashx/?Callback=DocumentReadStatus",
  {
      userID: vuserID,
      documentID: vdocumentID,
      format: "json"
  },
  function(result) {
      if (result.readStatus == '1') {
          alert("ACCEPTED");
      }
      else if (result.readStatus == '0') {
          alert("NOT ACCEPTED");
      }
      else {
          alert(result.readStatus);
      }
  });

FYI: while development of this locally, everything worked fine, but after solution deployment to server and trying to do the same, I got that problem.

Also, I tried the same functionality with web service, I got the same problem while calling web service from server.

I'm using ajaxSetup to detect thrown errors.

$.ajaxSetup({ "error": function(XMLHttpRequest, textStatus, errorThrown) {
    alert("textStatus: " + textStatus);
    alert("errorThrown: " + errorThrown);
    alert("responseText: " + XMLHttpRequest.responseText);
 } 
});
