I've seen something like this:

The requests module http://docs.python-requests.org/en/latest/
ships with its own set of certificates "cacert.pem"
and ignores the system wide ones -- so, for instance, adding certificates
to /etc/ssl/certs on your debian or ubuntu system won't work.  I edited
it by hand and then changed the REQUESTS_CA_BUNDLE environment variable
to point to it.

Perhaps your problem is along the same lines?
