installed application throws CertificateHostnameMismatch #346

[Use this form for both apiclient and oauth2client issues]
I have a Google Service Account which is being used by an installed application 
to upload files into GCS, and then send a POST request to a GAE Module.

The upload of files to GCS works great, but when the credentials of the default 
service account are used to send a POST to a GAE Module (in its yaml file the 
login for the GAE Module handler is declared to be required), the 'Server 
presented certificate does not match' the URI

After searching this site, as well as using Google Search, I have not 
discovered a solution to this problem, and not much general info about this 
type of problem. I'm using the latest version of the Goolge API Python client 
(1.9.24)

Here's the stack trace:

What steps will reproduce the problem?
1. Running the code
2.
3.

What is the expected output? What do you see instead?
See stack trace shown above. Source code is attached. And the yaml of the 
target GAE Module is included as well (if that is of any help).

What version of the product are you using? On what operating system?
Product version 1.9.24. Windows 7 Professional 32-bit

Please provide any additional information below.
This is my first attempt at sending a POST request to a GAE Module from an 
installed application, so my guess is I've got an easily detected bug in my 
code, or I'm entirely missing some critical bit of code.

FYI, 
I have worked past this problem by making the following change to the code:
http_auth = credentials.authorize(httplib2.Http())
is now:
http_auth = 
credentials.authorize(httplib2.Http(disable_ssl_certificate_validation=True))

But, doing so has resulting in the repressing the prior certificate error 
message, while triggering another error (likely caused by my code, which I am 
now investigating):

    headers['user-agent'] = self.user_agent + ' ' + headers['user-agent']

Hopefully, I'll resolve this one shortly.
