Загрузка картинки и отправка в чат Telegram

Класс Bot:

    public class Bot extends TelegramLongPollingBot {
        private long chatId;
        Document document;
        Parser parser = new Parser();
    public void onUpdateReceived(Update update) {
        update.getUpdateId();
        chatId = update.getMessage().getChatId();
        Message msg = update.getMessage();
        if (msg != null && msg.hasText()) {
            //if(msg.getText().equals("/start")) {
            SendMessage sendMessage = new SendMessage().setChatId(chatId);
            try {
                sendMessage.setText(parser.ParseText(msg.getText()));
                execute(sendMessage);
            } catch (TelegramApiException e) {
                e.printStackTrace();
            }
            SendPhoto sendPhoto = new SendPhoto().setChatId(chatId);
            try {
                sendPhoto.setPhoto(parser.ParseImg(msg.getText()));
                execute(sendPhoto);
            } catch (TelegramApiException e) {
                e.printStackTrace();
            }
        }
    }

    public String getBotUsername() {
        return "@ParseSteamBot";
    }
    @Override
    public String getBotToken() {
        return "...";
    }
}

Класс Parser:

public File ParseImg(String href) {
    File file;
    try {
        document = Jsoup.connect(href).get();
        Elements img = document.getElementsByClass("game_header_image_full");
        try(InputStream in = new URL(img.attr("src")).openStream()){
            Files.copy(in, Paths.get("C\\images\\"));
            return new File("C\\images\\");
        }
        catch(IOException e){
            e.printStackTrace();
        }
    }
    catch(IOException e){
        System.out.println("Image not found...");
        e.printStackTrace();
    }
    return null;
}

Ошибки возникают в строках с блоком try...catch

Хотя при первом же запуске код сработал и загрузил одну картинку. Думаю, это блокировки со стороны сервера из-за частых запросов
