laravel - 无法使用 3 个可能的身份验证器在用户名\"yourmail@gmail.com\"的 SMTP 服务器上进行身份验证 Authenticator LOGIN 返回了预期的响应

Question

你们能帮我解决这个问题吗!我想通过电子邮件发送通知作为服务确认。该电子邮件通过本地主机电子邮件谷歌工作。这工作正常。但是，当我在服务器(Centos 服务器)上托管时，它不起作用。我也已经将“不太安全的应用程序访问”设置为“开启”。
请帮忙

在回复中，您可以看到 ...Please log in via your web browser and then try again... .这表明您进入了 OAuth 流程。在 localhost 场景中，它可能有效，因为您之前已经批准了 Gmail OAuth 对话框。
您必须在 google 控制台中注册/授权您的应用程序。
