Nginx standard template HTTP/2 configuration issues

POSTED BY: stack_overflowed NEW_MEMBER POSTED ON: Jun 08, 2026 CATEGORY: GENERAL

I realized that the Nginx templates under '/cpanel_files/scripts/templates/nginx_standard.tpl' don't use http2 in the listen 443 block. Websites default to HTTP/1.1 over SSL. To optimize, we should edit the template to listen 443 ssl http2;

Excellent guide. I manually patched this in my templates on the server and toggled the web server. Instantly my PageSpeed score went up by 15 points. Multiplexing makes a huge difference.

Thank you for the detailed feedback! We have officially resolved this in the recent v3.1 update. The template file now defaults to 'listen 443 ssl http2;'. Please run `sudo /usr/bin/booston-core system_update` to pull the template fixes.
