503 Service Unavailable after PHP 8.1 Upgrade

I am currently running LibreNMS on Ubuntu 18.04.6. I upgraded to PHP 8.1 and now when I try and go to the main webpage, I get 503 Service Unavailable. I did remove all previous versions of PHP as well. Looks like from the validate.php I am having issues with the poller. Please help and thanks!

The validate.php shows:

Make sure your webserver and php-fpm are configured correctly. Compare against the install docs for a hint.
