虽然我以前做过这个，但我不记得遇到过这个问题，所以我不明白我错过了什么步骤。
我正在尝试使用 certbot 为我的服务器创建 SSL 证书，但是，我在 acme_challenge 中遇到了失败。我遇到了“未授权”失败。问题是，我不知道如何在 DNS 中设置质询。当 certbot 运行时，我记得它会暂停并让你在 DNS 中设置质询，但这并没有发生。
它会将错误抛到显示挑战的终端窗口并表示挑战失败。输出如下。
root@systopian-web2:~# sudo certbot certonly --agree-tos --email [email protected] --webroot -w /var/lib/letsencrypt/ -d mydomain.tld -d www.mydomain.tld
