Apache Let's Encrypt Certbot 挑战在 Linux 上失败

我有一台运行 Apache Tomcat 的 Fedora 34 服务器。我拥有来自 Let's Encrypt 的证书。我使用 certbot 安装它们（就像一个人做的那样），一切运行良好。现在，当我去更新证书时，我收到以下错误：

[root@app myname]# certbot
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

IMPORTANT NOTES:
- The following errors were reported by the server:

   Domain: example.com

   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.
[root@app myname]#

更多详细信息：我有一个从 Apache Web 服务器到 Tomcat 的重定向 (mod_rewrite) 正在运行。我在故障排除期间暂时将其关闭。

答案1

我们找到了答案！这是一条错误的 DNS AAAA（ipv6）记录。我们修复了这个问题，然后 certbot 成功运行了！我们将 AAAA 记录指向服务器上 ifconfig 上显示的 ipv6 地址。我不确定它为什么最终指向了不同的地址。
