Connecting to mlab

Question

I am trying to connect to my database in mLab. I created an account of course, and a DB then added a user (crud). Then I tried connecting through mongo shell using this command:

$ mongo ds046027.mlab.com:46027/crud -u crud -p 123456

always end up facing this error:

MongoDB shell version v3.6.0
connecting to: mongodb://ds046027.mlab.com:46027/crud
2017-12-21T19:13:58.264+0300 W NETWORK  [thread1] Failed to connect to 
52.178.209.192:46027 after 5000ms milliseconds, giving up.
2017-12-21T19:13:58.265+0300 E QUERY    [thread1] Error: couldn't connect to 
server ds046027.mlab.com:46027, connection attempt failed :
connect@src/mongo/shell/mongo.js:251:13

exception: connect failed

I also tried using the string uri:

mongodb://crud:123456@ds046027.mlab.com:46027/crud

and this error comes up in my VS Code:

failed to connect to server [ds046027.mlab.com:46027] on first connect 
[MongoError: connect ETIMEDOUT 52.178.209.192:46027]

Note: connecting to the default localhost:27017 through mongod works just fine and I can access the database and do anything with it.

I have mongo 3.6.0 and I know it has some problems if that's one of them. how can I fix it?

UPDATE: These are all the steps I'm following, tell me if I'm missing something,

• Installed mongo 3.6.0 on windows 10
• Created a DB file inside the data file (it works with the local mongod)
• Created an Account: { user: "yousefGh", account: "yousefGh" }
• created a DB: crud
• added a user: crud, and this is its config at mLab: { "_id": "crud.crud", "user": "crud", "db": "crud", "roles": [ { "role": "dbOwner", "db": "crud" } ] }
• cmd: mongo ds046027.mlab.com:46027/crud -u crud -p 123456

hope you can find anything!!
