java发起下载 连接超时，但是wget指令可以下

Question

以下http下载方法 在线上 linux上连接超时 但是wget可以下载成功，ping域名也能平通 在本地也能下载成功 裂开

public void downLoad(HttpServletResponse response,String HTTP_URL, String filename) {
BufferedInputStream bis = null;
BufferedOutputStream bos = null;

        try {
            URL url = new URL(HTTP_URL);
            HttpURLConnection connection = (HttpURLConnection)url.openConnection();
            connection.setRequestMethod("GET");
            connection.setConnectTimeout(5000);
            connection.setReadTimeout(6000);
            connection.connect();
            int responseCode = connection.getResponseCode();
            System.out.println("responseCode=" + responseCode);
            if (responseCode == 200) {
                InputStream is = connection.getInputStream();
                bis = new BufferedInputStream(is);
                response.reset();
                response.setContentType("application/x-msdownload");
                response.setHeader("Content-Disposition", "attachment;filename=".concat(new String(filename.getBytes("GBK"), "ISO-8859-1")));
                OutputStream fos = response.getOutputStream();
                bos = new BufferedOutputStream(fos);
                boolean b = false;
                byte[] byArr = new byte[1024];

                int b1;
                while((b1 = bis.read(byArr)) != -1) {
                    bos.write(byArr, 0, b1);
                }

                bos.flush();
            }

            connection.disconnect();
        } catch (Exception var21) {
            var21.printStackTrace();
        } finally {
            try {
                if (bis != null) {
                    bis.close();
                }

                if (bos != null) {
                    bos.close();
                }
            } catch (IOException var20) {
                var20.printStackTrace();
            }

        }

    }
