CertificateError: hostname doesn't match

python ssl mechanize mechanize-python

I'm using a proxy (behind corporate firewall), to login to an https domain. The SSL handshake doesn't seem to be going well:

CertificateError: hostname 'ats.finra.org:443' doesn't match 'ats.finra.org'

I'm using Python 2.7.9 - Mechanize and I've gotten past all of the login, password, security questioon screens, but it is getting hung up on the certification.

Any help would be amazing. I've tried the monkeywrench found here: Forcing Mechanize to use SSLv3

Doesn't work for my code though.

If you want the code file I'd be happy to send.

You can avoid this error by monkey patching ssl:

import ssl
ssl.match_hostname = lambda cert, hostname: True
