Surprisingly I am using this for last 6 months and it didn't error earlier but now when I uploaded my built again on staging I got this error.

令人惊讶的是，我在过去 6 个月里一直在使用它，而且它没有更早出错，但是现在当我在登台时再次上传我的构建时，我收到了这个错误。

Any suggestions would be highly appreciated.

任何建议将不胜感激。

I just had this same problem.

我刚刚遇到了同样的问题。

It looks like the server is not able to ping the destination address.

服务器似乎无法 ping 目标地址。

I did a quick restart of my dev server and everything is back to normal.

我快速重启了我的开发服务器，一切恢复正常。

Hope that helps.

希望有帮助。

Use below code in .envfile:

Try to clear cache, config cache, and restart apache2.

尝试清除cache，config cache和restart apache2。

It works.

有用。

After modify your settings you need to run: php artisan config:cache

修改您的设置后，您需要运行：php artisan config:cache

Without those laravel will use old ones.

如果没有这些，laravel 将使用旧的。

The problem is actually a simple typo. In your .env file, change this:

问题实际上是一个简单的错字。在您的 .env 文件中，更改以下内容：

to this:

对此：
