Laravel 无法与主机smtp.googlemail.com建立连接[连接尝试失败]

我使用的是Laravel8，即使我通过StackOverflow和youtube搜索并尝试了所有方法，仍然会出现这个错误

1-我在gmail上启用了不太安全的应用程序

2-我在gmail上创建了2个身份验证，生成了应用程序密码并使用了它

但我仍然收到了这个错误，没有给gmail发送电子邮件

环境文件

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=587
MAIL_USERNAME= education123online@gmail.com
MAIL_PASSWORD= ' app password'
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=education123online@gmail.com
MAIL_FROM_NAME="${APP_NAME}"

将Mail.php文件更改为config文件夹中的此文件，因为您错误地获取了.env常量

        'default' => env('MAIL_MAILER', 'smtp'),
  'mailers' => [
    'smtp' => [
        'transport' => 'smtp',
        'host' => env('MAIL_HOST', 'smtp.gmail.com'),
        'port' => env('MAIL_PORT', 465),
        'encryption' => env('MAIL_ENCRYPTION', 'ssl'),
        'username' => env('MAIL_USERNAME'),

感谢您的回复！但我已经打开了不太安全的应用程序访问，tls或ssl仍然显示错误预期响应代码220，但得到了带有消息“”的代码“”，它在我使用tls时显示了此错误，这是唯一的区别，而不是上面的区别。请从.env变量中删除空格，例如：MAIL\u DRIVER=smtp MAIL\u HOST=smtp.gmail.com MAIL\u PORT=465 MAIL\u USERNAME=education123online@gmail.comMAIL\u PASSWORD='app PASSWORD'MAIL\u ENCRYPTION=tls MAIL\u FROM\u地址=education123online@gmail.com寄自_NAME=“${APP_NAME}”'default'=>env（'MAIL_MAILER'，'smtp'），'mailers'=>['smtp'=>'smtp'，'host'=>env（'MAIL_host'，'smtp.gmail.com'），'port'=>env（'MAIL_port'，465），'encryption'=>env（'MAIL_encryption'，'ssl'），'username'=>env（'MAIL_username'），'password=>env（'MAIL_PASSWORD'），'timeout'=>null，'auth_mode'=>null，]，实际上问题是在你的配置文件中，你没有得到你正在得到的环境常数。如果你的环境常数包含特殊字符，那么你必须使用quotesthanks进行回复，应用程序密码只是充满了普通字符。虽然我厌倦了在密码上使用引号，但仍然一样error@kareem.i有posted我的答案。你可以根据我提供的更改环境配置。如果有任何问题，请告诉我
