Laravel script 503 Service Unavailable

I used litespeed on cyberpanel. add this website on this server. setup a Laravel web script. To run this script need PHP 8.1 I install PHP 8.1 and set this to this website. but still 503 Service Unavailable.

Welcome @mdshehan Happy you are here

Considering you are using PHP I believe this is a PHP sessions issue. Just run as sudo user:

# deletes php 8.1 session folders and recreates them
$ rm -rf /var/lib/lsphp/session/lsphp81; mkdir -p /var/lib/lsphp/session/lsphp81; chmod 1733 /var/lib/lsphp/session/lsphp81

have you solved?
