I am trying to get joomla to work on nginx with postgresql. But i get this error in the error.log of nginx. I am running AlmaLinux8

This is when i just enter my ip into the browser.

My nginx conf file:

}

The weird thing is, is that i can access every other file within de root folder like readme and a test.php file i made. Those work file but index.php just doesn't work.
