As you can see from the traceback, this is an issue with requests, not the SDK.

You could try upgrading your version of requests, as suggested in
https://github.com/kennethreitz/requests/issues/2028.

Tried for like 2 hours how to fix this problem and its impossible.

And i have the certs.py and certs.pyc that come with requests in the same folder.. i cant find the solution!

[Justin Grayston]

I just had the same error, that showed itself as soon as GAE SDK handled a request. When running unit tests it was fine.

What solved it was simple. I hadn't added ssl in the app.yaml under libraries

libraries:

- name: jinja2

  version: latest

- name: webapp2

  version: latest

- name: markupsafe

  version: latest

- name: ssl

  version: latest

Then request that the SDK routed worked. I think either in the last version or one before that of the SDK the sandboxing got more strict and it unloads modules you won't have by default at runtime from sys.modules.

I hope this helps someone.

I owe you a beer Justin!

Thank you so much man. This cleared that error.
