but, The following error is occurring when accessing the web page.

Composer detected issues in your platform: Your Composer dependencies require a PHP version “>= 8.1.0”.

Firstly I would check if you have php 8.0 still running:

systemctl | grep php

If not then maybe ensure the timezone is set correctly:

vi /etc/php/8.2/fpm/php.ini
vi /etc/php/8.2/cli/php.ini

Finally confirm the PHP-FPM is configured correctly as per the install guide:

After all of this try a PHP service restart and then an update and validate of nms and see how you are going:

systemctl restart php8.1-fpm
su - librenms
./daily.sh
./validate.sh
