根据许多答案证书不绑定到IP地址，但绑定到域。 但是我仍然无法通过使用域来获得应用程序。 有没有办法通知DNS的IP已经改变。
当我尝试更新证书时，
./letsencrypt-auto certonly -w /etc/apache2/ssl/ -d mkt.example.com 我可以select
您如何使用ACME CA进行身份validation？ 我select了Apache，但我得到以下错误，
No vhost exists with servername or alias of: mkt.example.com. No vhost was selected. Please specify servernames in the Apache config
具有以下细节。
IMPORTANT NOTES: - The following errors were reported by the server: Domain: mkt.example.com Type: connection Detail: Failed to connect to 53.90.140.146:443 for TLS-SNI-01 challenge 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.
这里，以前的IP地址是53.90.140.146。 但是新的IP是另外一个。
那么我该如何解决这个问题
