Answer 1

Replace your code with this code:

const connectionURL = “mongodb://120.0.0.1:27017”;

And add useUnifiedTopology:true with useNewUrlParser:true

Answer 2

The error says "connection time out", what means either your server is very slow or there is no mongoDB at the specified ip%port. If I assume that correctly that your mongoDB is running on localhost, that you have an typo in your connectionURL .You set it to 120 .0.0.1. It should probably be 127 .0.0.1.

const connectionURL = "mongodb://127.0.0.1:2701" or const connectionURL = "mongodb://localhost:2701"
