Mongoose: Mongoose authentication fail when trying to connect to MongoDB Atlas

[emaxedon]

4818 Referencing this issue: it's closed but I am still reproducing the same problem.

Mongoose version: 4.9.2
Node.js version: 7.7.4
MongoDB Atlas version: 3.2

When trying to connect via mongo shell, everything works fine.

mongo 'mongodb://someUser:[email protected]:27017,someShard-shard-00-01-fjfvq.mongodb.net:27017,someShard-shard-00-02-fjfvq.mongodb.net:27017/someDb?replicaSet=someShard-shard-0&ssl=true&authSource=admin'

Here, I'm connecting to someDb, but I'm authenticating the user against the admin database.

When trying to connect with Mongoose I get the following error:

 { MongoError: authentication fail
at Function.MongoError.create ...

I'm thinking it's an error with it not handling the authSource properly. Mongoose successfully connects if I make admin the database I'm trying to connect to, but doesn't connect if I make admin the authSource I'm trying to authenticate against.

Any ideas?

Same problem here!

Mongoose version: 4.2.10
Node.js version: 6.9.5
MongoDB Atlas version: 3.4.2

When trying to connect via mongo shell, everything works fine, but when I trying from my express.js code, I get the following error:

name: 'MongoError', message: 'no valid seed servers in list'

Has anyone found a solution?

[emaxedon]

It for some reason works for me now. Can I see your code?

Hello @emaxedon , I am using MEANJS generator from Yeoman. Here is my code:
var config.db.uri = 'mongodb://myUser:[email protected]:27017,myCluster-shard-00-01-67fdt.mongodb.net:27017,myCluster-shard-00-02-67fdt.mongodb.net:27017/myDatabase?ssl=true&replicaSet=myCluster-shard-0&authSource=admin'

`var db = mongoose.connect(config.db.uri, function (err) {
// Log Error
if (err) {
console.error(chalk.red('Could not connect to MongoDB!'));
console.log(err);
} else {

  // Enabling mongoose debug mode if required
  mongoose.set('debug', config.db.debug);

  // Call callback FN
  if (cb) cb(db);
}

});`

It returns the following error:
Could not connect to MongoDB! { MongoError: no valid seed servers in list}

Using this same String, I can successfully connect via mongo shell. Until I find a solution, I'm using an old database from Xervo.io, but my actual database is already set in Atlas. Any ideas ?

@emaxedon did you change anything between when it was working and when it started working? And is it still working?

@gilalan @varunjayaraman

Not sure if it makes a difference - but the only thing I changed that made it work (no idea why this works) is the following.

const db = mongoose.connect(config.db.uri, {
    server: {
        socketOptions: {
            keepAlive: 1
        }
    }
}).connection;

db.on('error', (err) => {
    console.log(err);
});
db.once('open', (err) => {
    if (err) {
        console.log(err);
    } else {
        // ...
    }
});

Not changed for me =( i'm stucked with that error.
Anyway @emaxedon, thanks for your help!

I had the same issue like @gilalan. "name: 'MongoError', message: 'no valid seed servers in list'". I updated node to version v6.10.3 and mongoose to version 4.9.8. After these updates I was able to connect to Atlas via Mongoose.

@gilalan I can confirm that mongoose 4.2.10 cannot connect to MongoDB Atlas with the error message MongoError: no valid seed servers in list.

However, I can also confirm that upgrading to the latest mongoose (currently 4.9.8) fixed the issue, and enabled mongoose to connect to MongoDB Atlas.

I believe this issue should be closed.

It is fixed now! I don't know why but it's ok!.
