Проблема работы selenide с таймером

моя программа обновляет постоянно страницу в инстаграмме, через таймер, вот код:

public static void main(String[] args) {
        Configuration.browserPosition = "5000x5000";
        // TODO Auto-generated method stub
        System.setProperty("webdriver.chrome.driver", "C:\\Users\\"+System.getProperty("user.name")+"\\chromedriver.exe");// "C:\\Users\\"+System.getProperty("user.name")+"\\chromedriver.exe");
        System.setProperty("selenide.browser", "Chrome");

        open("https://www.instagram.com/accounts/login/?hl=ru");

        $(By.xpath("//*[@id=\"react-root\"]/section/main/div/article/div/div[1]/div/form/div[2]/div/label/input")).setValue("LOGIN").pressEnter();
        $(By.xpath("//*[@id=\"react-root\"]/section/main/div/article/div/div[1]/div/form/div[3]/div/label/input")).setValue("PASSWORD").pressEnter();
    $(By.xpath("/html/body/div[3]/div/div/div[3]/button[2]")).click();
     final ScheduledExecutorService ses = Executors.newSingleThreadScheduledExecutor();
     ses.scheduleWithFixedDelay(new Runnable() {
         @Override
         public void run() { Selenide.refresh();  }
     }, 2, 600, TimeUnit.SECONDS); 

но почему-то, на том моменте, когда начинает работать таймер, selenide перестает работать, и выбрасывает ошибку:

я пробовал делать таймер по другому:

 new java.util.Timer().schedule(new TimerTask(){
            @Override
            public void run() {Selenide.refresh();}
        },1000*2,1000*2);

но все так же, но вылетала другая ошибка
