    location /nested {      alias /var/www/nested/public;      try_files $uri $uri/ @nested;

     location ~ .php$ {      include snippets/fastcgi-php.conf;      fastcgi_param SCRIPT_FILENAME $request_filename;      fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;      }     }

    location @nested {      rewrite /nested/(.*)$ /nested/index.php?/$1 last;     }
