ArcGIS JavaScript API JSONP request

I am trying to add featues to esri.layers.FeatureLayer from response of JSONP request with esri.request. Interestingly I have right response and all features are perfectly shown on the map,BUT I get this error dojo.io.script error RequestTimeoutError: Timeout exceeded { message="Timeout exceeded", stack=".cache["dojo/errors/http://crea...cgis.com/3.12/:214:284\n", response={...}, more...} This is my code for requesting features from WFS server and adding them to layer:

 var layerDefinition = {
            "extent": {
                "xmin": 350000,
                "ymin": 6370000,
                "xmax": 750000,
                "ymax": 6630000,
                "spatialReference": {
                    "wkid": 3301
                }
            },
            "fields": [
                {
                    "name": "OBJECTID",
                    "type": "esriFieldTypeOID"
                }
            ]
        };
        var featureCollection = {
            layerDefinition: layerDefinition
        };
        var vectorLayer = new esri.layers.FeatureLayer(featureCollection);
        map.addLayers([vectorLayer]);
        var layerUrl = 'http://ift.tt/1uYMzh9;' +
                'version=1.1.0&request=GetFeature&typeName=ermas:testdata_geopnt&' +
                'outputFormat=text/javascript&format_options=callback:loadFeatures&maxFeatures=300&' +
                'srsname=EPSG:3301&EPSG:3301';
        var loadFeatures = function (response) {
            for (var i = 0; i < response.features.length; i++) {
                var geometry = new esri.geometry.Point(response.features[i].geometry.coordinates[0], response.features[i].geometry.coordinates[1], new esri.SpatialReference({ wkid: 3301 }));
                var symbol = new esri.symbol.SimpleMarkerSymbol();
                var graphic = new esri.Graphic(geometry, symbol);
                vectorLayer.add(graphic)
            }
        };
        window.loadFeatures = loadFeatures;
        var layersRequest = esri.request({
            url: layerUrl,
            callbackParamName: "loadFeatures"
        });

and if I try this>

layersRequest.then(
            function(response) {
                console.log("Success: ");
            }, function(error) {
                console.log("Error: ");
            });

it also prints ERROR.

Ant help to find my mistake??
