Nginx url工作时LetsEncrypt certbot超时错误

我将它与nginx一起使用。使用

.well-known/acme challenge

中的文件进行测试工作正常（请参阅），并创建文件。以下是错误：

$ certbot certonly --webroot -w /var/www/ghost -d devpy.me -d www.devpy.me -d

grunt.devpy.me

   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. 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.

grunt.devpy.me和devpy.me被重定向到www.devpy.me。尝试续订也会出现同样的问题。

你有没有想过？有完全相同的问题。是的，我想我只是暂时关闭了服务器，只托管了Webert。出现干扰。是否暂时关闭服务器？就像你刚刚重启一样？到目前为止，这是我还没有尝试过的一件事。我正在努力使这件事得到证实。我以前也做过其他事情，没有遇到过这样的麻烦。你知道吗？有完全相同的问题。是的，我想我只是暂时关闭了服务器，只托管了Webert。出现干扰。是否暂时关闭服务器？就像你刚刚重启一样？到目前为止，这是我还没有尝试过的一件事。我正在努力使这件事得到证实。我以前也做过其他事情，没有遇到过这样的麻烦。
