ssl - DNS NXDOMAIN 错误命令 certbot

Question

我正在尝试安装一个 ssl 证书，以便在我的域和我的子域中进行加密。 我在我的域上成功安装了 ssl 证书，但我在我的子域上没有成功 我使用下一个命令

certbot certonly --webroot -w /var/www/sub-domain/maxime-mazet.fr/owncloud/ -d cloud.maxime-mazet.fr

/var/www/sub-domain/maxime-mazet.fr/owncloud 有我的代码的文件夹。
cloud.maxime-mazet.fr 是我的子域。

我的域 maxime-mazet.fr 是 ovh 的主机。 对于 cloud.maxime-mazet.fr，我已经使用服务器的 IP 创建了输入 A。

我的域 (maxime-mazet.fr) 没有错误，但我的子域 (cloud.maxime-mazet.fr) 错误是

   cloud.maxime-mazet.fr

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address. Additionally, please check that
   your computer has a publicly routable IP address and that no
   firewalls are preventing the server from communicating with the
   client. If you're using the webroot plugin, you should also verify
   that you are serving files from the webroot path you provided.

谢谢你的帮助

Answer 1

ns13.ovh.net 和 dns13.ovh.net 似乎不是您域名的权威，因为它们没有正确回复对它的查询。您首先需要解决该问题。询问 OVH 它们是否确实是用于您的域的正确主机。由于您最近似乎刚刚对域名进行了一些更改，您可能只需要稍等片刻即可解决问题。
