Php 使用Laravel，SMTP邮件无法在Live Server中工作

我的配置在本地主机上运行良好。电子邮件成功地通过了。但当我将其部署到live server上时，Laravel给了我以下错误：

Whoops, looks like something went wrong.

在my laravel/app/config/mail.php中

<?php

return array(

| Mail Driver

*/

'driver' => 'smtp',

/*

/*
|--------------------------------------------------------------------------
| SMTP Host Port
|--------------------------------------------------------------------------

*/

'encryption' => 'tls',

发生了什么事？你能帮帮我吗，谢谢

在我的例子中，我在live中使用了加密作为ssl和驱动器作为sendmail

检查以下事项

这是我的邮件工作邮件配置

正确生成密钥

"php artisan key:generate"

如果您的get“需要OpenSSL扩展”错误

对.env的权限

error.log是怎么说的？消息是“哎呀，好像出了什么问题”。在哪里可以找到error.log？

MAIL_DRIVER=smtp
MAIL_HOST= smtp.gmail.com 
MAIL_PORT=587
MAIL_USERNAME=demo@gmail.com // email id that working and capable to send mails
MAIL_PASSWORD=test123 
MAIL_ENCRYPTION=tls

"php artisan key:generate"

enable the openssl extension by opening php.ini.

sudo chown -R www-data pathto/.env
