证书最初可能是通过 certbot certonly --manual（手动交互模式）申请的，这种方式需要人工操作（如手动添加DNS记录或HTTP验证文件）。
自动续订时，Certbot 会尝试使用相同的插件（manual），但非交互模式下必须通过 --manual-auth-hook 提供自动化验证脚本，否则会失败。

解决方案
如果不需要手动验证（如DNS验证），改用 webroot 或 standalone 模式重新申请证书：

删除旧证书配置：
bash
sudo certbot delete --cert-name <sitedomain>
重新申请证书（以 webroot 模式为例） ：
bash
sudo certbot certonly --webroot -w /var/www/html -d <sitedomain>
-w /var/www/html: 指定网站根目录（根据你的实际路径修改）。
-d <sitedomain>: 你的域名。
后续自动续订：
bash
sudo certbot renew --quiet
webroot 模式无需停止Web服务，适合自动化续订。
☁  ~  sudo certbot delete --cert-name <sitedomain>

WARNING: Before continuing, ensure that the listed certificates are not being
used by any installed server software (e.g. Apache, nginx, mail servers).
Deleting a certificate that is still being used will cause the server software
to stop working. See https://certbot.org/deleting-certs for information on
deleting certificates safely.
