Сокеты Android не работают только в рабочем режиме

Я пытаюсь отправить сообщение через сокеты Android, но всякий раз, когда я пытаюсь открыть сокет в режиме выполнения, я просто получаю SocketException. Вот strackTrace:

А вот мой код:

public class UnconfiguredDeviceCheckTask extends AsyncTask<String,Void,Integer>{

    final static String DEFAULT_DEVICE_IP = "192.168.4.1";
    final static int DEFAULT_DEVICE_PORT = 7510;
    final static String REQUEST_DEVICE_CHECK = "C8\r";

    private AsyncResult resultCallback;
    private int resultCode = 0;

    public UnconfiguredDeviceCheckTask(AsyncResult result){
        resultCallback = result;
    }

    @Override
    protected Integer doInBackground(String... strings) {
        try{
            Log.i("Wifi","Sleeping");
            Thread.sleep(5000);
        }catch(InterruptedException e){
            Log.i("Wifi","Async connection task is interrupted while sleeping");
        }
        try {
            Log.i("Wifi","Attempting to open socket");
            Socket socket = new Socket(DEFAULT_DEVICE_IP, DEFAULT_DEVICE_PORT);
            try {
                BufferedInputStream in = new BufferedInputStream(socket.getInputStream());
                try{
                    PrintStream out = new PrintStream(socket.getOutputStream());
                    out.write(REQUEST_DEVICE_CHECK.getBytes());

                    socket.setSoTimeout(10000);
                    while(resultCode == 0) {
                        resultCode = in.read();
                        Log.i("Wifi","Setting result code to " + resultCode);
                    }
                }catch (IOException e){
                    Log.e("Wifi","Could not create PrintStream");
                }
            }catch (IOException e){
                Log.e("Wifi","Could not create inputStream");
            }


            Log.i("Wifi","No response, Connection timed out");

        }catch (IOException e){
            Log.e("Wifi","Unable to create socket to 192.168.4.1");
            e.printStackTrace();
        }
        return resultCode;
    }

Однако сокет открывается нормально в режиме отладки, когда точка останова установлена ​​там, где создается сокет. Я не понимаю, как это исправить. Любая помощь?
