Сеть недоступна при использовании активного режима FTP на носимом устройстве

В настоящее время я пытаюсь разработать носимое приложение, которое может загружать файлы с данными акселерометра и гироскопа на мой компьютер через FTP.

Я использовал следующий код для запуска FTP-сервера на моем ПК в Eclipse:

public static void main(String[] args) throws FtpException {

    ListenerFactory listenerFactory = new ListenerFactory();
    listenerFactory.setPort(2221);

    PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();
    UserManager userManager = userManagerFactory.createUserManager();
    BaseUser user = new BaseUser();
    user.setName("Anonymous");
    user.setPassword("");
    user.setHomeDirectory("C:\\temp");  

    List<Authority> authorities = new ArrayList<Authority>();
    authorities.add(new WritePermission());
    user.setAuthorities(authorities);
    userManager.save(user);

    FtpServerFactory factory = new FtpServerFactory();
    factory.setUserManager(userManager);
    factory.addListener("default", listenerFactory.createListener());

    FtpServer server = factory.createServer();
    server.start();
}

Я использую этот метод для подключения к FTP-серверу:

public void connectToFTPServer() throws IOException {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

    StrictMode.setThreadPolicy(policy);
    Log.i("CONNECT FTP SERVER", "Connecting to FTP Server");
    ftpClient.connect(server, port);
    ftpClient.login(user, pass);
    ftpClient.enterLocalActiveMode();
    ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
}

И этот метод для загрузки данных датчика:

public void uploadFileTest()throws IOException {
    try
    {
        if (ftpClient.login("Anonymous", ""))
        {
            String data = this.getFilesDir() + "/" + "SensorData.txt";

            FileInputStream in = new FileInputStream(new File(data));
            boolean result = ftpClient.storeFile("SensorData.txt", in);
            in.close();
            if (result) Log.v("upload result", "succeeded");
            ftpClient.logout();
            ftpClient.disconnect();
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

Носимое устройство работает на эмуляторе в Android Studio, и даже если кажется, что соединение с FTP-сервером установлено, я получаю следующее сообщение об ошибке на FTP-сервере, когда пытаюсь загрузить данные датчика.

Пожалуйста, помогите мне, я часами искал возможное решение. Я уже разрешил порт в брандмауэре Windows и пробовал другие подходы.

Спасибо вам всем.
