PyMongo MongoDB Cloud Atlas and Python 2.7.2 can't connect

[Benoît HERVIER]

Hi,

I'm currently trying to connect to a mongodb cloud Atlas instance, while the code is working fine on desktop with py2.7.12. I can't auth with Python 2.7.2 on iOS or Android, I got a ServerSelectionTimeoutError.

1/ how can I get details of this error to understand what happen really in background ?

2/ Does pymongo3.4 support Python 2.7.2 ?

Thanks

Python versions before 2.7.9 have various problems with TLS/SSL that have to be solved through third party packages. Assuming you are using PyMongo 3.3 or later, you can install any necessary dependencies like this:

python -m pip install pymongo[tls]

If you're curious what the extra packages are, or you're using an older 3.x version of PyMongo and have to install the extra packages manually:

Thanks Bernie,

I m alreading importing certifi, i can now reproduce the error using python 2.7.2 also on desktop.

I use the following snippet

uri = "mongodb://user:pa...@cluster0-shard-00-00-ycpfg.mongodb.net:27017,cluster0-shard-00-01-ycpfg.mongodb.net:27017,cluster0-shard-00-02-ycpfg.mongodb.net:27017/datas?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&ssl_ca_certs="+certifi.where()

db_storage = pymongo.MongoClient(uri)
db_storage.admin.command('ismaster')

I m probably doing something wrong, but i dont understand what.

Thanks

I use the following example :

http://api.mongodb.com/python/2.9.4/atlas.html

But something look like missing for 2.7.2.

Thanks

You might be hitting this python bug, which was reported in Python 2.7.2:

http://bugs.python.org/issue13034

There is no changelog entry for the fix, so it's not clear what version of 2.7 the fix was released in, but it was clearly 2.7.3 or later.

If you post the traceback you're getting, I can confirm.
