nano /etc/nginx/sites-available/default

server {  
        server_name wpcademy.com www.wpcademy.com;
        listen 443 ssl http2 default_server;
        root /var/www/html;
        index index.html;

       server_name    domain.com www.domain.com;
       return         301 https://$server_name$request_uri;
}
