用于 aws EC2 Flask 应用程序的 ssl

Question

我从 freenom.com 注册了一个免费域名，并从 AWS route53 添加了名称服务器。现在我的域<blabla>.ga 成功重定向到 EC2 python 烧瓶服务器。但我真的不知道如何使用让加密添加 ssl。我正在关注链接https://ivopetkov.com/b/let-s-encrypt-on-ec2/ 对我的 ec2 进行 SLLifying。运行letsencrypt-auto 后我添加域名并按回车，然后我得到

[ec2-user@ip-172-31-40-218 letsencrypt]$ cd /opt/letsencrypt/
[ec2-user@ip-172-31-40-218 letsencrypt]$ ./letsencrypt-auto

Unable to find a virtual host listening on port 80 which is currently needed for Certbot to prove to the CA that you control your domain. Please add a virtual host for port 80.

here 提出了类似的问题，但我已经在两个答案中做了大部分解释。任何人都可以帮助我解决我在这里缺少的东西吗？

尝试以下教程：

https://www.digitalocean.com/community/tutorials/how-to-deploy-a-flask-application-on-an-ubuntu-vps

确保您能够在没有 https 的情况下访问上述网络应用程序，然后尝试安装 SSL。如我所见，您遇到以下错误

无法找到正在侦听端口 80 的虚拟主机，Certbot 目前需要该虚拟主机向 CA 证明您控制您的域。请为 80 端口添加虚拟主机。

一定有一些配置问题。请调试它并告诉我。
