It would be very helpful if you post your current code.

#3 
mongoose

.connect(process.env.MONGO_URI,{useNewUrlParser:true,useUnifiedTopology:true})

.then(console.log('Connected to MongoDB'));

and it stands in the console

connectid to mongoDB

#4

(node:2173) UnhandledPromiseRejectionWarning: MongooseError: The uri parameter to openUri() must be a string, got “undefined”. Make sure the first parameter to mongoose.connect() or mongoose.createConnection() is a string.

In VS Code was working fine no err…

#6

And I rfresh it it throws now this
Connected to MongoDB
events.js:291
throw er; // Unhandled ‘error’ event
^

Error: listen EADDRINUSE: address already in use :::3000
