【中文标题】以前部署到 Heroku 时可以工作的 KeystoneJS V4 应用程序现在停止工作 - MongoDB Atlas

【英文标题】：KeystoneJS V4 app that used to work when deploying to Heroku is now stopped working - MongoDB Atlas

【问题描述】：

由于堆栈更改，Heroku 删除了几个月前与 MongoDB Atlas 完美连接的 KeystoneJS V4 应用程序。现在我正在尝试使用正确的配置部署相同的应用程序，但出现部署错误。这是我得到的错误：

请有人帮我解决这个问题。不知道为什么我会收到这个错误。我有正确的 MONGODB_URI（在另一个应用上可以正常工作）。

【参考方案1】：

该错误 (failed to connect to server) 直接来自 Mongoose，因此这是数据库连接的问题。原因可能是……

网络

Atlas 默认阻止所有流量；对于 Heroku 部署，您需要通过配置 access list 来打开它。在这种情况下，它应该包含类似0.0.0.0/32 的内容以允许所有 IP。 （我知道你说过可以从另一个应用程序访问数据库，但仍然值得检查。）

授权

URI 是否包含用户名密码？它应该是……

mongodb+srv://<username>:<password>@cluster-1z703hln.tt6wq.mongodb.net/my-app?retryWrites=true&w=majority

.. 或类似，不是 Atlas 为 CLI 建议的较短形式，例如。

mongodb+srv://cluster-1z703hln.tt6wq.mongodb.net/my-app

当您尝试从开发机器上的mongo 客户端连接时会发生什么？它可能会提供更有用的错误消息。

【讨论】：

谢谢。网络 - 是的，它已经配置为使用 0.0.0.0/0 访问数据库以允许所有 IP。 Auth - 是的，URI 格式正确，UN & PW 正确。用于访问另一个应用程序的相同。唯一的区别是，先前的错误之一建议删除 +srv。所以它以 mongodb:// 开头 - 我之前遇到过这个问题，在删除 +srv 之后，它才让连接到数据库。

@billgajen 你的意思是0.0.0.0/32 对吗？ 0.0.0.0/0 将阻止一切。除此之外，我没有想法。您是否尝试在您的开发机器上从 Mongo 客户端（如 mongo cli）进行连接？

嗨@molomby，最后这个答案帮助解决了这个问题：***.com/questions/59778351/…。谢谢
