AJAX request on the server

AJAX request does not work when on server ... locally runs normal ... Anyone have any idea what it can be?

function SalvarPedido() {

    //Data
    var data = $("#Data").val();

    //Cliente
    var cliente = $("#Cliente").val();

    //Valor
    var valor = $("#Valor").val();

    var token = $('input[name="__RequestVerificationToken"]').val();
    var tokenadr = $('form[action="/Pedido/Create"] input[name="__RequestVerificationToken"]').val();
    var headers = {};
    var headersadr = {};
    headers['__RequestVerificationToken'] = token;
    headersadr['__RequestVerificationToken'] = tokenadr;

    //Gravar
    var url = "/Pedido/Create";

    $.ajax({
        url: url
        , type: "POST"
        , datatype: "json"
        , headers: headersadr
        , data: { Id: 0, Data: data, Cliente: cliente, Valor: valor, __RequestVerificationToken: token }
        , success: function (data) {
            if (data.Resultado > 0) {
                ListarItens(data.Resultado);
            }
        }
    });
}
