Hey guys, I have the following problem,
I have tested the connection using Mongo Client in my project and I was able to connect my DB on MongoDB Atlas, but when I use mongoose it says was unable to connect.

Can you share your code?

require(‘dotenv’).config();
var mongoose = require(“mongoose”);
const uri = process.env[‘MONGO_URI’];
mongoose.connect(uri, { useNewUrlParser: true, useFindAndModify: false,
useUnifiedTopology: true });

ENV:

MONGO_URI=“mongodb+srv://username:password@cluster.mongodb.net/test?retryWrites=true&w=majority”

Response:

MONGO_URI=“mongodb+srv://username:password@cluster.mongodb.net/test?retryWrites=true&w=majority”

Did you replace username with your actual username and password with the matching password? What about the name of the database and the cluster?

Have you followed steps similar to that in this video?

I did it, worked! I need to change the “package,json”, and get the more recent version of MongoDB(^4.1.3), mongoose(^6.0.9), and Express(^4.17.1), and worked fine, thanks for the help, I really appreciate it.
