Finally found it: It appears that requests does not work on app engine so well, but there is a fix: https://github.com/kennethreitz/requests/compare/master...agfor:master

and this is where i took it from

If you're using requests in Google App Engine, it's recommended you use requests_toolbelt aswell.

You can read more about it here.

In your code, just use

from requests_toolbelt.adapters import appengine
appengine.monkeypatch()
