How can I troubleshoot a socket connection error from python to Splunk? (SSL: CERTIFICATE_VERIFY_FAILED)

[manus]

I'm doing my first python script connecting to Splunk. It fails with following error:

Traceback (most recent call last):  
  File "PrintInterntalIndexEventCount.py", line 14, in <module>  
    password=PASSWORD,scheme=scheme)  
  File "C:\Python27\lib\site-packages\splunklib\client.py", line 305, in connect  
    return Service(**kwargs).login()

    response = self.handler(url, message, **kwargs)

    self.connect()

  File "C:\Python27\lib\ssl.py", line 350, in wrap_socket
    _context=self)
  File "C:\Python27\lib\ssl.py", line 566, in __init__
    self.do_handshake()
  File "C:\Python27\lib\ssl.py", line 788, in do_handshake
    self._sslobj.do_handshake()
ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)

Here is the script

import splunklib.client as client

HOST = "lonsl1101443.uk.net.intra"
PORT = 8089
USERNAME = "user"
PASSWORD = "pwd"
scheme="https"

service = client.connect(
    host=HOST,
    port=PORT,
    username=USERNAME,
    password=PASSWORD,scheme=scheme)

for app in service.apps:
    print app.name  

If someone has the slightest idea about why this could fail, that would help!

The proxy in our network is failing to verify the host certificate and hence not able to establish handshake.
After bypassing the host verification on the proxy we were able to connect to AWS endpoints.

The problem was my python version install.
It doesn't work with: Python 2.7.9 64bit and Python 2.7.9 32bit.
It works with 2.7.8 32 Bit

Thank you, that was driving me crazy!
