我有一个自托管网站，最近我的 SSL 证书过期了。
尝试使用命令创建一个新的sudo certbot certonly -d 'example.com,*.example.com' --manual --preferred-challenges dns。该命令运行时不会出现问题，但会产生以下错误，并产生以下输出：
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for example.com and *.example.com
Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/example.com/fullchain.pem
Key is saved at: /etc/letsencrypt/live/example.com/privkey.pem
This certificate expires on 2023-05-09.
These files will be updated when the certificate renews.
NEXT STEPS:
- This certificate will not be renewed automatically. Autorenewal of --manual certificates requires the use of an authentication hook script (--manual-auth-hook) but one was not provided. To renew this certificate, repeat this same certbot command before the certificate's expiry date.

但是，当我用例如检查时，它仍然不起作用。https://www.sslshopper.com/，它仍然显示过期的证书。我等了一天多了，还是没有任何动静。
旁注：我没有设置任何 TXT 记录，certbot 没有要求我设置，就像上次一样
