Mongolab/pymongo Connection Error

If I run in the shell: mongo ds0219xx.mlab.com:219xx/dbname -u user -p pass It works and allows me to connect to the database and pull information. But if I'm within my python app

Solution 1:

I figured it out. You can do this from the python file and it will work:

connection = pymongo.MongoClient(ab123456.mlab.com, 123456)
db = connection[databasename]
db.authenticate(database_user, database_pass)

Solution 2:

Appending /?authSource=admin helped me. Full Example:

uri = 'mongodb://username:password@r1.example.net:27017/?authSource=admin'

client = MongoClient(uri)
db = client.test

result = db.users.find()

for document in result:
    print(document)

Version: pymongo 3.7.2

Solution 3:

You need to authenticate after selecting the database for mongo < 4.0
