Certbot-auto 更新失败 - 客户端缺乏足够的授权 - 为什么？

Question

因此，我在同一台服务器(Apache 2.2 - Debian 7)上为多个域放置了一个 certbot-auto 证书已经有好几年了。但是今天我看到我的 crontab 没有更新证书，所以我尝试在 SSH 中使用以下行进行更新:

./certbot-auto renew

这是错误声明:

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A/AAAA record(s) for that domain
   contain(s) the right IP address.
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.

我没有更改有关 Vhost 配置或服务器配置的任何内容，所以我不知道为什么 certbot 不再具有自动更新功能。

EDIT :

所有域都有一个 A记录在 DNS使用正确的 IP。

我的 /.well-known/文件夹当前的权限为 0777。

Answer 1

我找到了一个替代解决方案，但我没有解决问题。

我做了像here这样的技巧:
我使用了以下命令:

./certbot-auto certonly -d www.domain1.fr -d domain1.fr -d domain2.fr -d www.domain2.fr

我的证书现在又可以工作了。

所以问题(我想)是方式 certbot-auto renew匹配每个网站的 webroot。

非常感谢@Martin Zeitler 的帮助和您的时间。
