Redirect to login page with message not working in laravel 5.3

When registering for external link, I want to dislay a message :

 if (!Auth::check()){
        Session::flash('message', trans('msg.please_create_account_before_playing', ['tournament' => $tournament->name]));
        return redirect(URL::action('Auth\LoginController@login'));
    }

In my login page, I have:

@if (Session::has('message'))
   <div class="alert alert-info">
    <button type="button" class="close" data-dismiss="alert"><span>×</span><span class="sr-only">Close</span></button>
    </div>
@endif

I checked in my login page, with laravel debugbar, and there is no message var in session. But it never shows up...

Any idea why it is not working?
