CloudPanel version(s) affected

2.5.2

Description

The default virtual host (vhost) templates in CloudPanel 2.5.2 are configured to enable HTTP/3 and QUIC by default. However, the bundled nginx version (nginx version: nginx/1.21.4) on Ubuntu 22.04 LTS does not support QUIC/HTTP3, which can cause configuration errors or prevent Nginx from starting correctly after provisioning a site.

How to reproduce

  1. Install latest CloudPanel 2.5.2 on Ubuntu 22.04 LTS
  2. Add new site (example: asd.com)
  3. Go to Vhost tab and just hit Save
  4. CloudPanel returns an error

Vhost is not valid, error message: nginx: [emerg] invalid parameter "quic" in /etc/nginx/sites-enabled/asd.com.conf:4 nginx: configuration file /etc/nginx/nginx.conf test failed

Possible Solution

No response
