收到错误"MongooseServerSelectionError: Server selection timed out after 30000 ms"

Question

我得到了错误MongooseServerSelectionError: Server selection timed out after 30000 ms。我正在使用MongoDB Atlas。我已经尝试将useUnifiedTopology更改为false，我的应用程序没有崩溃，但我得到了错误DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.

整个错误信息：

MongooseServerSelectionError: Server selection timed out after 30000 ms

type: 'ReplicaSetWithPrimary',

stale: false,
compatible: true,
compatibilityError: null,
logicalSessionTimeoutMinutes: null,
heartbeatFrequencyMS: 10000,

}
}

我的Mongoose代码：

const dbOptions = {
useNewUrlParser: true,
autoIndex: false,
poolSize: 5,
connectTimeoutMS: 10000,
family: 4,
useUnifiedTopology: true
};

mongoose.connect('mongodb+srv://Wolfgang:[e-mail]/Wolfgang?retryWrites=true&w=majority', dbOptions);
mongoose.set('useFindAndModify', false);
mongoose.Promise = global.Promise;

如何修复/绕过此问题？

根据我使用这种eror的经验，我认为您的连接URL有问题。尝试如果您使用windows或robomongo，请尝试在MongoDB指南针中使用相同的连接URL。

您也可以尝试检查：

MongoDB连接错误：MongoTimeoutError：服务器选择在30000毫秒后超时

MongoTimeoutError:连接到mongoDB 时，服务器选择在30000毫秒后超时

服务器选择在10000毫秒后超时-无法将Compass连接到localhost 上的mongoDB
