Laravel 11 Database Connection Error: Access denied for user 'root'@'127.0.0.1' (Hostinger)

I'm encountering a database connection issue in my newly hosted Laravel 11 application on Hostinger. I've carefully configured the files and database in phpMyAdmin, but I'm getting this error:

SQLSTATE[HY000] [1045] Access denied for user 'root'@'127.0.0.1' (using password: NO)

this is my .env file configuration:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=crm_db
DB_USERNAME=root
DB_PASSWORD=
