Ошибка сокета при выполнении простого HTTP-запроса и разборе выходных данных в объект InputStream

Question

Я пытаюсь вызвать HTTP-запрос и проанализировать ответ в InputStream.Это простой публичный сервер.

Я использую Fedora 30 с последней версией Android Studio.Любые идеи, почему я получаю эту ошибку сокета?

public static String getResponseFromHttpUrl(URL url) throws IOException {
        HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
        try {
            InputStream in = urlConnection.getInputStream();

            Scanner scanner = new Scanner(in);
            scanner.useDelimiter("\\A");

            boolean hasInput = scanner.hasNext();
            if (hasInput) {
                return scanner.next();
            } else {
                return null;
            }
        } finally {
            urlConnection.disconnect();
        }
    }

Вот вывод ошибки:
