Question

该错误是间歇性的，有时它有效，有时它不起作用，这使得调试非常困难。

作为Stream的联合创始人之一，我可以告诉你，在我们这一端，事情进展顺利:)您也可以从 Stream 的状态页面进行验证。

您遇到的超时错误可能取决于很多事情。以下两个是类似问题的最常见原因：

>

本地开发人员和我们的APIendpoint之间的连接延迟缓慢/不一致

DNS问题（如DNS TTL处理错误、DNS服务器损坏等）

我的建议是通过以下方式确保两者都得到照顾：

> < li>

为您的开发环境增加API超时，在stream-laravel配置文件中确保您有< code>'timeout' =

确保你使用像谷歌DNS这样的东西（它们工作得很好），IP是8.8.8.8和8.8.4.4由于Homestead使用Ubuntu，你可以参考这个链接
