Python erreur client 'Connexion réinitialisée par l'homologue'

J'ai écrit un très petit client python pour accéder à l'api reposant de confluence. J'utilise le protocole https pour me connecter à la confluence. Je rencontre Connection reset by peer Erreur. Voici la trace complète de la pile.

/Users/rakesh.kumar/.virtualenvs/wpToConfluence.py/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:318: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.

Voici mon code client:

import requests


def main():
    auth = open('/tmp/confluence', 'r').readline().strip()

    username = 'rakesh.kumar'

    response = requests.get("https://<Host-NAME>/rest/api/content/",
                            auth=(username, auth),
                            headers={'content-type': 'application/json'})
    print response

if __name__ == "__main__":
    main()

J'exécute ce script dans un environnement virtuel et les packages suivants sont installés sur cet environnement:

(wpToConfluence.py)➜  Python pip list
You are using pip version 6.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
appnope (0.1.0)
backports.shutil-get-terminal-size (1.0.0)
decorator (4.0.10)
ipdb (0.10.1)
ipython (5.0.0)
ipython-genutils (0.1.0)
pathlib2 (2.1.0)
pexpect (4.2.0)
pickleshare (0.7.3)
pip (6.1.1)
Prompt-toolkit (1.0.5)
ptyprocess (0.5.1)
Pygments (2.1.3)
requests (2.10.0)

simplegeneric (0.8.1)
six (1.10.0)
traitlets (4.2.2)
urllib3 (1.16)
wcwidth (0.1.7)

Il se plaint du numéro de version python mais je ne sais pas comment mettre à jour mon environnement Mac/Virtual python.

J'ai essayé de boucler la commande et Postman tous les deux fonctionnent bien pour les paramètres donnés.

Lors de l'installation de la bibliothèque requests, elle ignore quelques-uns des packages de sécurité facultatifs ('pyOpenSSL', 'ndg-httpsclient' et 'pyasn1') qui sont requis pour la connexion SSL/Https. Vous pouvez le corriger en exécutant cette commande

pip install "requests[security]"

ou

pip install pyopenssl ndg-httpsclient pyasn1
