Cannot login to cwp as root

[balron]

After the fresh install , I have changed root password by ssh terminal passwd command, Now i cannot login to cwp panel
It says login failed but i can login to server via ssh with new root password.

What is the issue? Is it bug or do i need to run some sh script to update cwp or something else?
I have double check the url is correct : serverIP:2031/login/index.php

It is running on CentOS 9
