Не работает ServerSocket на Heroku

Никакой реакции.Приложение деплоится.Но на клиенте ошибки при подключении. Также делал проверку на PING , чтобы быть уверенным в свободности портов, но ничего не происходит.

Статистика Ping для 54.217.217.151: Пакетов: отправлено = 5, получено = 0, потеряно = 5 (100% потерь)

Весь код :

public class Server implements Runnable{
    ServerSocket socket=null;
    Socket socket2=null;
    ObjectOutputStream out = null;
    public static void main(String[] args){
        Thread t = new Thread(new Server());
        t.start();
    }
    @Override
    public void run() {
        try {
            socket = new ServerSocket(55519);    
            socket2 = socket.accept();
            DataOutputStream dt = new DataOutputStream(new ObjectOutputStream(socket2.getOutputStream()));
            while(true){           
                dt.write(21312333);
            }    
        } catch (UnknownHostException e) {
        } catch (IOException e) {
        } catch (HeadlessException e) {

        } 
    }
}

А вот клиентский код :

package paket;

public class Client{
    ObjectOutputStream out = null;
    public static void main(String[] args) throws UnknownHostException, IOException {
        Socket s = new Socket("appname.herokuapp.com",55519);
        DataInputStream dtinput = new DataInputStream(new ObjectInputStream(s.getInputStream()));
         if(s.isConnected()){
             System.out.println("isConnected");
             System.out.println(dtinput.read());
             dtinput.close();
             s.close();
         }
    }

}

heroku-logs : только я пару раз открывал в браузере последние логи возможно из-за этого.
