连接到MSSQL Windows Azure Laravel 5时出错

I'm working on a project that needs to be connected to a MS SQL Database, I have a cloud database which is hosted in Microsoft Azure, I can access it using SQL Server Management Studio, however in my Laravel project when I tried to query I get . I already allowed my IP Address in the Azure Firewall.

PDOException in Connector.php line 47: SQLSTATE[08001]: [Microsoft][SQL Server Native Client 11.0]Named Pipes Provider: Could not open a connection to SQL Server [2]. 

Here's my config

'azure' => [
        'driver'    => 'sqlsrv',
        'host'      => env('DB_HOST', 'ybefh1h7kh.database.windows.net,1433'),
        'database'  => env('DB_DATABASE', 'test'),
        'username'  => env('DB_USERNAME', 'myuser'),
        'password'  => env('DB_PASSWORD', 'password'),
        'prefix'    => '',

    ],

My query

$users = DB::connection('azure')->select("SELECT * FROM Users");
var_dump($users);exit;

use this

'azure' => [
    'driver'    => 'sqlsrv',
    'host'      => 'ybefh1h7kh.database.windows.net,1433',
    'database'  => 'test',
    'username'  => 'myuser',
    'password'  => 'password',
    'prefix'    => '',

],
