Problems with ajax on the server

I have an application on ZF2 on Ubuntu server. One of the controllers is triggered from a ajax request.

Locally, the application works normally. However, when uploading to the server I started having problems: the request is sent as POST, but I can not get the data in the controller, because it arrives as GET and with the data array empty.

Would anyone know what the problem is, since the same code works in the local environment?

No controller o get of data:

$data = $this->getRequest()->getPost()->toArray();
            $request = $this->request;
            $post = array_merge_recursive(
                    $request->getPost()->toArray(), $request->getFiles()->toArray()
            );
            $postData = array();
            $error = array();
            $errSuccess = array();

            //get Query String
            parse_str($post['data'], $postData);

In html I have the following code:

wizard.on("submit", function (wizard) {

            var formData = new FormData();
            formData.append('upload', $('input[type=file]')[0].files[0]);

            var ins = document.getElementById('gallery').files.length;
            for (var x = 0; x < ins; x++) {
                formData.append('gallery[]', $('input[type=file]')[1].files[x]);

            }

            formData.append('data', wizard.serialize());

            $.ajax({
                type: "POST",
                url: '/advertiser/add',
                data: formData,
                cache: false,
                contentType: false,
                processData: false,
                success: function (resp) {
                    if (resp.response == 1) {
                        $(".create-server-name").text($("#nome_razao").val());
                        wizard.submitSuccess();
                        wizard.hideButtons();
                        wizard.updateProgressBar(0);
                        $.each(wizard.cards, function (name, card) {
                            card.el.find("input").val(); // resets all inputs on a card to ""
                        });
                    } else if (resp.response == 2) {
                        var str = '';
                        for (obj in resp.result) {
                            str += "<li>" + resp.result[obj] + "</li>";
                        }
                        $(".create-server-name").text($("#nome_razao").val());
                        $('#errmsg').html(str);
                        console.log(str);
                        wizard.submitSuccess();
                        wizard.hideButtons();
                        wizard.updateProgressBar(0)
                        $.each(wizard.cards, function (name, card) {
                            card.el.find("input").val(); // resets all inputs on a card to ""
                        });
                    } else {
                        var str = '';

                        $('#errmsgerr').html(resp.result);
                        console.log(str);
                        wizard.submitError();
                        wizard.hideButtons();
                        wizard.updateProgressBar(0)
                    }
                },
                error: function () {
                    wizard.submitFailure();
                    wizard.hideButtons();
                },
            });

        });
