Downgrade to 2.11.1 is a fix …

@skob Please please please read the other comments in this thread before posting. I have asked all people reporting to do an investigation and so far no-one has.

Let me be clear: any furthe “me too” posts that don’t acknowledge the investigation I have asked people to do will be summarily deleted.

@larryhq Can you please do the investigation I outlined above?

To anyone else who hits this issue, please don’t just say “me too”. Please investigate this issue as outlined above, because right now none of the maintainers can reproduce the bug.

I have the same problem (even after reinstalling pyopenssl and cryptography).

The problem goes away when I rollback requests to 2.11 and comes back when I upgrade to 2.12 (or the current dev version)

Reinstalling pyopenssl does not help

So it is definitely part of requests (or it dependency description).

I’ve just closed this because it’s now clear that all of these issues stem from having an out-of-date PyOpenSSL in your Python environment. If you encounter this issue, please update your PyOpenSSL to at least 0.14.

I had this issue, and resolved it by doing this. After verifying a clean virtualenv works with only a ‘pip install requests’

sudo yum uninstall python-requests sudo pip uninstall pyopenssl cryptography requests sudo pip install requests
