  I followed an article from cPanel that helped. Procedure To enable this globally, add a new file ending in .conf such as http2.conf to the Nginx configuration folder located in /etc/nginx/conf.d and add the following contents. server { listen 443 ssl http2; listen [::]:443 ssl http2; } Save the file and verify the Nginx configuration. Then, restart Nginx as well as PHP-FPM. nginx -t /scripts/restartsrv_nginx ; /scripts/restartsrv_apache_php_fpm I then checked my file: tail -f /var/log/nginx/access.log and it showed: HTTP/2.0 Even gtmetrix reported all is good now with http2 :)
