title: Pymodm connect to an mlab MongoDB
body: <p>I have a MongoDB database hosted on mlab and I would like to use <a href="http://pymodm.readthedocs.io/en/stable/getting-started.html" rel="nofollow noreferrer">PyMODM</a> as my object modeling library. </p>
  
  <p>This is my code so far: </p>
  
  <pre><code>from pymodm import connect, MongoModel, fields
  
  
  connect = connect('mongodb://user:pass@ds119788.mlab.com/db')
  
  class Test(MongoModel):
      user = fields.CharField()
  
  
  if __name__ == "__main__":
      test = Test("test")
      test.save()
  </code></pre>
  
  <p>But it gives me this error : </p>
  
  <p><code>pymongo.errors.ServerSelectionTimeoutError: ds119788.mlab.com:27017: [Errno 61] Connection refused</code></p>
  
  <p>Am I missing something? </p>
