Error connecting to Mongodb Atlas from Google Colaboratory

Question

I am unable to connect to Mongodb Atals from Google colab notebooks. Establishing the connection does not return any errors, but any attempt to read or write data returns the error:

[Errno -5] No address associated with hostname.

Below is the simple code I am using. Can anyone help?

client = pymongo.MongoClient("mongodb://[username]:[password]@mongodb-ihjrm.mongodb.net/?retryWrites=true")
db = client.mytestdb
mycol = db.mytestcol

mydict = { "name": "John", "address": "Highway 37" }
x = mycol.insert_one(mydict)

Go to mongo atlas -> Security->Database accesses and change the role of the user to atlasAdmin. Works perfectly!!!!!!
