mongoDB Atlas ♥︎ Sailsjs (waterline sails-mongo adapter) - mongodb

Question

i just created a MongoDB Atlas account.
I'm using sails with waterline sails-mongo adapter
but I can't manage to connect via my app.
Everything is up to date.
I can connect to any other DB (localhost, digitalocean server, ...)
I can also connect to that MongoDB Atlas Database via their tool (MongoDB Compass) and via shell with the mongo cmd
but it seems like sails-mongo is just not working with that db, which requires a very up-to-date mongo version
Is someone else using MDB Atlas && sailsjs ?
(I thought about refactoring my app, but it's starting to be huuge and it just seems impossible to use the "mongodb" adapter)
Versions :
- node : 6.3.1
- npm : 3.10.6
- mongo (shell) : 3.4.2
- sails-mongo npm module : sails-mongo#0.12.2

Hey people thanks to your tips and SailsJS team I was able to figure out a few things that can help you fix this issue (I was able to):
Update your sails-mongo to v0.12.3 npm install sails-mongo#0.12.3 --save
Update sails-mongo's mongodb dependency to v2.2.25. You can do this editing package.json. That version includes a fix for replicaSets connections: https://github.com/mongodb/node-mongodb-native/commit/915d5c8a765151fb14942445a92d92a0e9e9c942#diff-88dc7475eedf918122374be6d7c2c151R12
Make sure that the mongodb's mongodb-core version is at least v2.1.9.
Now I went directly and created my connection like this:
{
adapter: 'sails-mongo',
url: 'mongodb://user:pass#server-1.mongodb.net:27017,server-2.mongodb.net:27017,server-3.mongodb.net:27017/test?ssl=true&replicaSet=server-&authSource=admin',
ssl: true
}
Yes, you need to add the ssl parameter again.
By looking at the sails v1.0 code, lost of this things will be fixed by that update ;) Thanks SailsJS Team!

You hit the nail on the head -- the current sails-mongo adapter for Sails v0.12.x uses a version of the native MongoDB driver that doesn't support all the features required to work with Atlas (e.g. authSource). See this issue on Github.
We're finishing up the last bits on the sails-mongo adapter for Sails 1.0, which supports the latest options and has been tested successfully with Atlas, so now might be a good time to start preparing to upgrade to version 1.0. After Sails 1.0 is released we'll only be doing bug fixes and security patches to modules that work with v0.12.x.

The error message suggests that the connection is timing out. Step one would be to check your configuration, is it correctly populated with this format in config/connections.js?
// MongoDB is the leading NoSQL database.
// http://en.wikipedia.org/wiki/MongoDB
//
// Run:
// npm install sails-mongo
//
someMongodbServer: {
adapter: 'sails-mongo',
host: 'localhost',
port: 27017,
// user: 'username',
// password: 'password',
// database: 'your_mongo_db_name_here'
},
If it's not your configuration, it's likely an incompatibility with your version of sails, sails-mongo, or Mongo DB. Which versions of these are you running?
