MongoLab/PyMongo connection error
12,860
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:[email protected]:27017/?authSource=admin'
client = MongoClient(uri)
db = client.test
result = db.users.find()
for document in result:
print(document)
Version: pymongo 3.7.2

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 application (Flask) and run this:
import pymongo client = pymongo.MongoClient("mongodb://user:[email protected]:219xx/dbname") db = client["dbname"] db.users.insert_one({ "user1": "hello" })
It gives me an:
pymongo.errors.OperationFailure: Authentication failed.
I'm pretty sure it's failing before it gets to the insert_one() call, but I'm not completely sure.
Thanks!
Edit: By request, here is the full callback:
