Laravel passport 获取 token 时无响应

代码都是安装站主写的一样但是每次都卡在
$response = $http->post(url()->previous().'/oauth/token',

    [
        'form_params'=> [
            'grant_type' => 'password',
            'client_id' =>env('CLIENT_ID'),
            'client_secret'=>env('CLIENT_SECRET'),
            'username'=>$name,
            'password'=>$password,
            'scope'=> $scope,
        ],
    ]);

获取$response处,也不报错,其他请求也进行不了
