我将我的站点迁移到另一个托管站点，并且自迁移后此错误开始发生。我正在使用 Laravel 8.31.0，我正在尝试向我网站上的用户发送电子邮件，但在发送“Swift_TransportException”时收到此错误响应 身份验证模式 1 无效”。请注意，在迁移之前，它在我以前的托管站点上运行良好。

我已经联系了我的托管站点的开发团队，他们推荐了一些我尝试过但仍然无效的修复程序，我也在这里看到了一些修复程序，我已经尝试过，但仍然没有工作，请问我该如何解决这个问题？我是 Laravel 的新手 这是我的 .env 文件的样子：

此外，我在编辑我的 .env 文件后确实使用了“php artisan config:cache”，因此它绝对不是缓存问题
