Cannot connect by mongoDB Atlas URI using mongoose in node

Question

I am trying to connect my atlas cluster URI in my node project Node version: 12.4.1 mongoose: 5.2.7

this is how my URL looks alike

mongoose.connect(mongodb+srv://usernane:pass@uri/db_name?authSource=db_name&w=1, {
        useCreateIndex: true,
        keepAlive: 1,
        useNewUrlParser: true,
        useFindAndModify: false,
        useUnifiedTopology: true
    });

I am facing error authentication failed, What I am doing wrong any help will be appreciated.

Answer 1

The format and/or query parameters of the connection string you've provided for MongoDB Atlas looks incorrect. Please ensure, the format is as follows:

mongodb+srv://<username>:<password>@<cluster-id>.mongodb.net/<db-name>?retryWrites=true&w=majority

(The above is taken from MongoDB Atlas connection example)

If, after the above correction - you still face auth issues, I suggest checking with details and possibly create a test user from your Atlas dashboard - docs on authentication .

Answer 2

First things first, i prefer to await the connect method, to handle any possible errors. So something like:

try {
  await mongoose.connect('mongodb://localhost:27017/test', { useNewUrlParser: 
  true});
} catch (error) {
  handleError(error);
}

Secondly, if password contains special characters, they should be URL encoded. You can use this tool: https://www.urlencoder.org/

Finally, in my case, i did not know i had to allow my current ip address to mongoDB atlas. While in atlas:

1. click on your cluster then on the left side
2. under security click Network access
3. on the right click ADD IP ADDRESS.

This should fix it.
