Laravel邮件错误Swift_TransportException

Question

我正在尝试使用laravel邮件制作联系表。它在localhost上运行良好，但是当我在godaddy共享主机上托管时，我返回了一个错误：Swift_TransportException 无法与主机smtp.gmail.com建立连接[拒绝连接＃111]

我已经尝试了StackOverflow上几乎所有可用的解决方案。但是，它并没有解决问题。

MailController.php

class MailController extends Controller {
   public function send(Request $request){

        $this->validate($request, [
            'name'     =>  'required',
            'email'  =>  'required|email',
            'message' =>  'required'
        ]);

        $data = array(
            'name'      =>  $request->name,
            'message'   =>   $request->message
        );

        Mail::to('mail@gmail.com')->send(new SendMail($data));
        return back()->with('success', 'Thanks for contacting us!');
   }
}
