Database [mysql2] not configured Laravel?

message: "Database [mysql2] not configured."

My database configuration file is:

    'connections' => [
        'mysql2' => [
                'driver' => 'mysql',
                'host' => '92.113.183.90:3306',
                'port' => '3306',
                'database' => 'xxxxxx',
                'username' => 'xxxxxx',
                'password' => 'xxxxxx',
                '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'),
                ]) : [],
            ],
    ]

I have cleared cache and rerun server.
