我已经苦苦思索了几个小时，并在 SE 上遇到了很多类似的问题。然而，我还是无法解决我的问题。
回答这些显而易见的问题：
- 我的 ec2（ubuntu）实例上运行没有防火墙
- 443 端口已开放供进出
- 使用创建的 .ssl 文件
sudo certbot certonly --standalone - 非加密请求工作正常
- 我已将域的 A 记录设置为指向我的 EC2 实例的公共 DNS。但是没有命名空间记录选项。
- 是的，我是个白痴
除了添加以下内容之外，我没有触碰过 nginx.conf 文件：
include /etc/nginx/sites-enabled/*;
我的 nginx-conf 在 /etc/nginx/sites-available/myapp.conf 中（在...../sites-enabled/myapp.conf 中有符号链接）：
server {
listen 80;
listen 443 default ssl;
ssl_certificate /etc/letsencrypt/live/mydomain/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mydomain/privkey.pem;
server_name mydomain;
location /static/ {
autoindex on;
alias /home/ubuntu/MYAPP/static/;
}
location /data/ {
autoindex off;
alias /home/ubuntu/MYAPP/data/;
}
location / {
include proxy_params;
proxy_pass http://unix:/home/ubuntu/MYAPP/app.sock;
}
}
在我的 APPS 的 settings.py 中我添加了：
ALLOWED_HOSTS = [
'localhost',
'127.0.0.1',
'mywebsite.com']
目前，我已注释掉以下内容
#SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
#SECURE_SSL_REDIRECT = True
#SESSION_COOKIE_SECURE = True
#CSRF_COOKIE_SECURE = True
发行nc -vz localhost 443给予Connection to localhost 443 port [tcp/https] succeeded!
netstat -ntlp给出

尝试通过 https://... 访问我的域名导致超时。
编辑：正如 Steffen 指出的那样，我的 curl 命令是错误的。这是正确的命令
curl -v https://localhost:443
导致

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and

现在，/var/log/nginx/error.log 没有显示任何错误。
/var/log/nginx/access.log
当我尝试在浏览器中通过 https 打开时，没有显示任何请求。仅使用 http，请求就会被记录下来。所以看起来请求甚至没有到达 nginx，对吗？
我以前从未使用过 nginx（或任何与服务器/后端相关的东西），而且我完全不知道。
EDIT2：我需要弹性 IP 才能工作吗？有什么建议吗？
