MongoError: connection 0 to localhost:27017 timed out

Well there is no error during connection, but when try to save some models/collections it runs for a while and then it throws this error. BTW I also have another node process connected to the same mongodb server. Any help is highly appreciated.
好吧，连接过程中没有错误，但是当尝试保存一些模型/集合时，它会运行一段时间，然后抛出此错误。顺便说一句，我还有另一个节点进程连接到同一个 mongodb 服务器。任何帮助都受到高度赞赏。

const mongoose = require('mongoose');
const option = {
socketTimeoutMS: 30000,
keepAlive: true,
reconnectTries: 30000
};
const mongoURI = process.env.MONGODB_URI;
mongoose.connect(mongoURI, option).then(function(){
//connected successfully
}, function(err) {
//err handle
});

Your query is taking a long time. And mongo itself has a default time out set. So it times out, if the query takes longer than the timeout time.
您的查询需要很长时间。并且 mongo 本身有一个默认的超时设置。所以它超时，如果查询花费的时间超过超时时间。

you have to use this configs on your connection: keepAlive: 300000, connectTimeoutMS: 30000
你必须在你的连接上使用这个配置：keepAlive: 300000, connectTimeoutMS: 30000

If you are sure that you exported port -p 27017:2017and it still doesn't work.
如果您确定您导出了端口-p 27017:2017，但它仍然不起作用。
Check your VPN if it is not blocking Local Network sharing.
检查您的 VPN，如果它没有阻止本地网络共享。
