Ajax POST fails on Firefox, works on Chrome

In order to load result from a POST request (which might take up to a minute or two to complete) while showing the user a load screen I am using an Ajax request. This seems to work fine on Chrome, but on Firefox the request fails with an unspecified error after a few seconds, before the server is able to return the response. This appears to happen especially when the server is running on localhost.

 $(document).ready(function() {
     $.post({
         url: "/analyze/",
         data: {
             "data": "data",
         },
         dataType: "html",
         cache: false,
         timeout: 60000,
         success: function(response) {
             $("#container").html(response);
         },
         error: function(jqXHR, textStatus, errorThrown) {
             $("#status").html("<div>Something failed!</div>");
         }
     });
 });

Any idea how I can resolve this?

Did you try to use a vanilla javascript ajax request `XMLHttpRequest()` ? – Core972 Jul 21 '18 at 23:18
Try using `url: "analyze/",` – mscdeveloper Jul 21 '18 at 23:38
Instead of putting `Something failed!` in the status, put `textStatus` and `errorThrown` so you can see the error-details. – wazz Jul 22 '18 at 00:32
For brevity I removed it, but I do log in console both. textStatus is "error" while errorThrown is empty. – C. G. Jul 22 '18 at 07:49

Using XMLHttpRequest does not seem to make any difference. – C. G. Jul 22 '18 at 08:09
