它是连接到URL的示例Java客户端。从http url读取成功后，https调用正在重置Connection。附件是上面代码的调试文件，这里有什么问题？我在防火墙的生产环境中工作，我已经创建了打开端口443和80的规则。
代码段：
URL url = new URL("https://app.leanix.net");
URLConnection con = url.openConnection();
final Reader reader = new InputStreamReader(con.getInputStream());
final BufferedReader br = new BufferedReader(reader);
String line = "";
while ((line = br.readLine()) != null) {
System.out.println(line);
}
br.close();
