MongooseServerSelectionError：连接 ECONNREFUSED 127.0.0.1:27017。 我已经尝试过 StackOverflow 中给出的所有解决方案，但它不起作用

}

I have used 'mongod' also.
I have created a folder also in my C:\data\db
used 127.0.0.1 also, instead of localhost

I don't know why this error is still there, after trying so many solution. How can I resolve it?

Answer 1

I am running this on Windows and my task manager had stopped this service and it was not starting automatically. That's why it was not running.

If you also got the same error just check by:

1. Type "services" in Windows search bar
2. Open it and scroll upto the mongoDB service
3. Start/restart it manually if its stopped.
