Jsoup抓取谷歌数据，出现connect timeout，求大神！！！之前还好好的。后面突然抛出这个错

public static List<JsoupBean> jsoup(String keywords) throws IOException {

        List<JsoupBean> list = new ArrayList<JsoupBean>();

        System.out.println("开始抓取！");

        String url = "https://www.google.com.hk/search?safe=strict&hl=zh-CN&tbs=qdr:m&lr=lang_zh-CN%7Clang_zh-TW&site=webhp&source=hp&q="+keywords;//Google

        System.out.println("抓取关键字为："+keywords);

        System.out.println("抓取地址为："+url);

        Document doc = Jsoup.connect(url).timeout(6000).header("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2").get();

        Elements rs = doc.select("h3.r>a");

        for (Element element : rs) {

            JsoupBean bean = new JsoupBean();

            if (element != null && element.parent() != null && element.parent().nextElementSibling() != null) {

                Elements cites = element.parent().nextElementSibling().select("cite");

                for (Element cite : cites) {

                    Element span = cite.parent().nextElementSibling();

                    if (cite != null && cite.parent() != null && span != null) {

                        String describe = span.text().equals("") || span.text() == null ? null :  span.text();

                        bean.setDescribe(describe);

                        String html = cite.text().equals("") || cite.text() == null ? null :  cite.text();

                        bean.setHtml(html);

                    }

                }

            }

            String title = element.text();

            bean.setTitle(title);

            list.add(bean);

        }

        System.out.println("抓取结束！");

            return list;

    }

  /*插入数据操作*/
