Проблемы HTTPS при использовании cloudflare и ubuntu 16.04 LEMP WordPress

Во-первых, позвольте мне сказать, что я новичок в вещах системного администратора, и это сайт, на котором я использую для получения практики и опыта.

У меня есть SSL через cloudflare, и я загрузил его в /var/ssl/ssl.pem и /var/ssl/ssl.key . Я изменил права доступа к папке на chmod 700 / var / ssl.

Я могу получить доступ к своему сайту через http://165.227.182.40/ и http://aaronstone.io/ , но не через https://aaronstone.io /

Моя конфигурация NginX выглядит следующим образом:

server {
    listen 80;
    listen [::]:80;

    # SSL configuration
    #
     listen 443 ssl;
     listen [::]:443 ssl;
         ssl_certificate /var/ssl/ssl.pem;
        ssl_certificate_key /var/ssl/ssl.key;

    root /var/www/html/;

    # Add index.php to the list if you are using PHP
    index index.php index.html index.htm index.nginx-debian.html;

    server_name aaronstone.io www.aaronstone.io;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        #try_files $uri $uri/ =404;
        try_files $uri $uri/ /index.php$is_args$args;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
             location ~ \.php$ {
        include snippets/fastcgi-php.conf;

        # With php7.0-cgi alone:
        #fastcgi_pass 127.0.0.1:9000;
        # With php7.0-fpm:
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    location ~ /\.ht {
        deny all;
    }
    location ~ /.well-known {
        allow all;
    }
}
