Why are the .env settings not being applied?

Question

Laravel

Installed VDS with nginx, php-fpm, mysql, etc.
Zipped a folder with Laravel, uploaded via FTP, made unzip. I created a user and a database in mysql, I change the access to the database in .env to
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=admin_laravel
DB_USERNAME=admin_admin
I do php artisan migrate
I get [1045] Access denied for user 'root'@'localhost' ( using password: NO)
I do php artisan config:clear
I get the same thing, why?
Perhaps it was necessary to do config:clear on the local machine before copying to VDS?

Maybe. What prevents it from being done on VDS?
