Database + Shared server + Laravel

Very good people,

I have the following doubt; I have a project in Laravel (v5.6 with php v7.2) connected to a local database and I want to reconnect it to the database of a shared server (CDMON).

From what I understand, I have to modify the data in the .env and /config/database.php files of my project. But once this is done, I miss the error corresponding:

It's as if it kept pointing me to the database I had before.

My .env file:

DB_CONNECTION=mysql
DB_HOST=192.xxx.x.xxx
DB_PORT=3306
DB_DATABASE=reporting
DB_USERNAME=mywel6902
DB_PASSWORD=xxxxxxx

My file " /config/database.php ":

'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', '192.xxx.x.xxx'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'reporting'),
        'username' => env('DB_USERNAME', 'mywel6902'),
        'password' => env('DB_PASSWORD', 'xxxxxxx'),
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'strict' => true,
        'engine' => null,
    ],

How do I tell him to point me to the new database? Should I clean the server's cache?

Thanks to everyone in advance.
