Multiple database in Laravel with a remote database - php

Question

I'm doing a PHP Laravel (7.7.1) project with a mariadb database (10.4.12).
Actually, I'm trying to use a remote mariadb database (10.1.44) on a virtual private server under Debian Stretch (9.11) with my local mariadb database (10.4.12) under Macos Catalina (10.15.4).
The problem is that my Laravel project can't access to the remote database, I saw that the best solution is to use a ssh tunnel but no one solution worked for me.
Here is my .env file
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=name
DB_USERNAME=username
DB_PASSWORD=password
DB_CONNECTION_GAME=mysql
DB_HOST_GAME=11.22.3.444
DB_PORT_GAME=3306
DB_DATABASE_GAME=name
DB_USERNAME_GAME=username
DB_PASSWORD_GAME=password
Here is my database.php file
'mysql' => [
'driver' => env('DB_CONNECTION', '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'),
]) : [],
],
'mysqlgame' => [
'driver' => env('DB_CONNECTION_GAME', 'mysql'),
'url' => env('DATABASE_URL_GAME'),
'host' => env('DB_HOST_GAME', '127.0.0.1'),
'port' => env('DB_PORT_GAME', '3306'),
'database' => env('DB_DATABASE_GAME', 'forge'),
'username' => env('DB_USERNAME_GAME', 'forge'),
'password' => env('DB_PASSWORD_GAME', ''),
'unix_socket' => env('DB_SOCKET_GAME', ''),
'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'),
]) : [],
],
Here is my database model
class Whitelisted extends Model
{
/**
* The attributes that are mass assignable.
* #var array
*/
protected $fillable = [
'name', 'identifier'
];
protected $connection = 'mysqlgame';
protected $table = 'user_whitelist';
}
And finnaly, here is the error code from Illuminate
SQLSTATE[HY000] [2002] Connection refused (SQL: select * from `user_whitelist`)
What is the best solution to have two databases with one local and the other connected to a remote server ?
Thanks !
