        ssl_certificate /etc/ssl/certs/nginx.crt;
        ssl_certificate_key /etc/ssl/private/nginx.key;

        server_name artofcse.local www.artofcse.local;
        index index.html index.htm index.php;
        root /var/www/artofcse.local;

        access_log /var/log/nginx/artofcse.local.access.log;
        error_log /var/log/nginx/artofcse.local.error.log;

        location / {
                try_files $uri $uri/ =404;
        }

        location /images {
                autoindex on;
                access_log /var/log/nginx/artofcse.local.images.access.log;
                error_log /var/log/nginx/artofcse.local.images.error.log;
        }

        location /appointments/ {
                allow 192.168.33.0/24;
                allow 10.0.0.0/8;
                deny all;
        }

        location /deny/ {
                deny all;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
                fastcgi_intercept_errors on;
        }

        error_page 403 /403.html;
        location = /403.html {
                internal;
        }

        error_page 404 /404.html;
        location = /404.html {
                internal;
