Flux CP installation page reloading

[Diana]

Hi 

I have a problem with fluxcp installation 

I configured application.php, servers.php

and when trying to install Flux CP and after clicking install it already creates the tables to the database but just reloading to the login page of Flux CP Install page ( that page we type the password we configured in application.php) 

I tried to change the php version from 7.3 to 7.5 to 5.2 but all version makes the same problem

using this updated version: https://github.com/rathena/FluxCP

What is the wrong?

check logs

1. check logs.
2. show errors.

or... possible https / issue ? or propagation ?

Errors/logs will show it better.

Only this shown:

<?php exit('Forbidden'); ?>

Already granted the permissions to the mysql username with the host ip

and tried to grant permission to everyone (%) and nothing changes.
