Error "Database [mydatabase] not configured." - Laravel - mysql

Question

I'm using Laravel, I'm working in a Login System, but in register page, when confirm button is clicked, I get the message: "Database [mydatabase] not configured."
My database.php file:
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
My .env file:
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=mydatabasename
DB_USERNAME=root
DB_PASSWORD=
My system and database are in a debian 9 server, and I programming in VS Code in my Windows Client with a extension remote for VSCode called SFTP. My database don't have password for now.
it may be an external access error to mysql, my version of MySQL is 10.4.11 and I am using it on the Debian 9 server with the latest current XAMPP version, and I don't know how to release external access to mysql in XAMPP, because in the my.cnf file there is no bind_address field.
This is just a hypothesis, I came here because I tried everything on Google and nothing works.
Thanks for listening! =D
Edit:
When I run the command "php artisan migrate":
root#LARAVEL:~/Projetos/SistemaX# php artisan migrate

Answer 1

Did you create the database and run Laravel's migrations?
To check if your database exist on your server, login to MySQL on your server and list all databases:
mysql -u yourusername -p
show databases;
Your Laravel database "mydatabasename" should be listed here. If not, you'll have to create it on your server. Since it's not specific to Laravel, I will let you search how to do that.
Once your database exists, you will have to run Laravel's migrations command to create the database tables relevant to your Laravel application:
php artisan migrate
