Залп нет ответа от HTTP GET

/ 28 апреля 2020

Я пытаюсь получить JSON из API, но ничего не получаю. JSON: 

{"coord":{"lon":90.41,"lat":23.71},"weather":[{"id":721,"main":"Haze","description":"haze","icon":"50n"}],"base":"stations","main":{"temp":25,"feels_like":28.6,"temp_min":25,"temp_max":25,"pressure":1011,"humidity":83},"visibility":3500,"wind":{"speed":1.5,"deg":90},"clouds":{"all":75},"dt":1588093825,"sys":{"type":1,"id":9145,"country":"BD","sunrise":1588029983,"sunset":1588076702},"timezone":21600,"id":1185241,"name":"Dhaka","cod":200}

Я добавил разрешение INTE RNET: 

<uses-permission android:name="android.permission.INTERNET" />

Мой код: 

    private void httpGet() {
    // Instantiate the RequestQueue.
    RequestQueue queue = Volley.newRequestQueue(this);
    String url = "https://api.openweathermap.org/data/2.5/weather?q=" + CITY + "&units=metric&appid=" + API;
    //https://api.openweathermap.org/data/2.5/weather?q=dhaka,bd&units=metric&appid=5694263c8d821570bfccff2a13246a73
    Log.d("TEST", "Fonction lancee 1/2" + url);

    JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
            (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    Log.d("TEST", "Fonction lancee 3/2" + response);
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.d("TEST", "Erreur");
                }
            });
    queue.add(jsonObjectRequest);
}

Я также тестировал с помощью StringRequest с тот же результат, без ответа.

РЕДАКТИРОВАТЬ Весь мой класс, чтобы увидеть контекст:

Вы можете проверить страницу моего JSON, адрес в комментариях в моем коде , (в городе запятая), работает.
