SSLError: EOF occurred in violation of protocol (_ssl.c:581)

I get this error both when using the library to make API calls and when using the requests library directly: SSLError: EOF occurred in violation of protocol (_ssl.c:581)

I am able to get a 200 response via curl and also when using the production api endpoint.

Nevermind, I googled around and it looks like installing a few additional packages will resolve this issue (although I don't understand what the core issue is). pip install pyopenssl pyasn1 ndg-httpsclient

This issue appears to be related to this:

https://github.com/kennethreitz/requests/blob/master/requests/packages/urllib3/contrib/pyopenssl.py

This specifies that in order to support SNI (and to use TLSv1.1 or greater) in Python 2.7.x using the requests library, you'll need to install the following dependencies:

pip install pyopenssl ndg-httpsclient pyasn1

That said, installing the above dependencies is a valid work around.

In case this helps others, I finally learned about this issue after receiving the following error:
ConnectionError: ('Connection aborted.', error(54, 'Connection reset by peer'))

Installing ndg-httpsclient and pyasn1 helped me.
pip install ndg-httpsclient pyasn1

The fix for this is to update Plaid's dependencies to install those bits appropriately:

install_requires['requests>=2.7.0'] => install_requires=['requests[security]>=2.7.0'] as requests declares this dependency

This is a relatively little-known dependency feature.
