Python/Requests: requests.exceptions.SSLError: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE]

In Python using MacOS X, made an attempt to make a POST request to a website but I got the following error post_response = session.post(post_url, data=post_payload, headers=post_headers):

Traceback (most recent call last):
  File "web_requests.py", line 424, in <module>
    main()
  File "web_requests.py", line 340, in main
    post_response = session.post(post_url, data=post_payload, headers=post_headers)
  File "/Library/Python/2.7/site-packages/requests/sessions.py", line 535, in post
    return self.request('POST', url, data=data, json=json, **kwargs)
  File "/Library/Python/2.7/site-packages/requests/sessions.py", line 488, in request
    resp = self.send(prep, **send_kwargs)
  File "/Library/Python/2.7/site-packages/requests/sessions.py", line 609, in send
    r = adapter.send(request, **kwargs)
  File "/Library/Python/2.7/site-packages/requests/adapters.py", line 497, in send
    raise SSLError(e, request=request)
requests.exceptions.SSLError: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:590)

What could be the issue?

Thank you in advance and will be sure to upvote/accept answer
