Braintree Connection Errors - 5 Attempt to get blocked socket option

[ankushchadda]

I am trying to use Braintree in my GAE app using devserver. However I am getting socket blocked errors. 

Below is the stack trace.

This seemed to be a https issue. I have tried different approaches

a) https://github.com/agfor/braintree-python-appengine . Gave me same error

b) I thought this could be the error from this issue -https://urllib3.readthedocs.org/en/latest/security.html#openssl-pyopenssl But on updating required libraries , I get stuck at OpenSSL.crypto failed import.

Any clues how to debug this?
