如何通过gunicorn和nginx在Django应用上使用certbot证书？

Question

我有一个运行在NGINX上的django应用程序，并成功创建了ssl证书，当我运行网络时，它超时了，并且启用了端口443。

server {
    server_name example.com www.example.com;

    access_log off;

    location / {
        proxy_pass https://127.0.0.1:8000;
        proxy_set_header X-Forwarded-Host $server_name;
        proxy_set_header X-Real-IP $remote_addr;
        add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
}


    listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
     if ($host = www.example.com) {
        return 301 https://$host$request_uri;
     } # managed by Certbot

     if ($host = example.com) {
         return 301 https://$host$request_uri;
     } # managed by Certbot


server_name example.com www.example.com;
    listen 80;
    return 404; # managed by Certbot

}

这是上面显示的/ etc / nginx / sites-available / mysite并正在运行sudo ufw状态输出
