Mongoose / MongoDB错误：无法确定服务器的状态

突然之间，我开始在本地运行我的应用程序时出现这个错误。 据我所知，上一次工作到现在，我没有任何改变。 它似乎是数据库层上的错误，因为它发生在应用程序试图做一些数据库相关的任务。

我试过升级节点，npm，mongoose，mongodb，我仍然得到相同的错误。

有很多我可以提供的信息，但我不知道什么是最相关的，所以让我知道还有什么需要帮助解决这个问题。

我也附加了我目前的package.json

事实certificate，当我切换到使用Yarn而不是NPM来处理模块时，我不知不觉地更新了我的Node版本。 我不得不安装节点v6.1.3。
