403禁止的错误-Java，Java.net.HttpURLConnection在aws-ec2机器上不工作，但在本地工作站上工作正常

尝试使用USER-AGENT属性，还添加了以下所有头以建立与SSL url的连接。403错误代码返回到服务器，但在本地工作站工作正常。 提前谢谢

HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
httpConn.setRequestProperty("Host", "www.sec.gov");
httpConn.setRequestProperty("User-Agent", "Mozilla/5.0 (X11; Ubuntu; Linux 
    x86_64; rv: 66.0) Gecko / 20100101 Firefox / 66.0 ");
httpConn.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
httpConn.setRequestProperty("Accept-Encoding", "gzip, deflate, br");
httpConn.setRequestProperty("Connection", "keep-alive");
httpConn.setRequestProperty("Upgrade-Insecure-Requests", "1");
httpConn.setRequestProperty("Pragma", "no-cache");
httpConn.setRequestProperty("Cache-Control", "no-cache");
httpConn.setRequestProperty("Accept", "*/*");
