Python requests.exceptions.SSLError: EOF occurred in violation of protocol

I would retrieve some information from an ABB G13 gateway that offer a RESTful JSON API. API is hosted by the gateway via https endpoint.Basic authentication mechanism is used for authentication. However all trafficgoes through SSL layers.

On linux with command:

curl -s -k -X GET -u user:password https://host/meters/a_serial/power

All goes well!

I'm trying to write a script for windows in Python 2.7.10 with Requests 2.8.1 and with this code:

import requestsrequests.get('https://host/meters/a_serial/power', auth=('user', 'password'))

I have this error:

Traceback (most recent call last):  File "C:/Users/mzilio/PycharmProjects/pwrgtw/test.py", line 20, in <module>    requests.get('https://host/meters/a_serial/power', auth=('user', 'password'))  File "C:\Python27\lib\site-packages\requests\api.py", line 69, in get    return request('get', url, params=params, **kwargs)  File "C:\Python27\lib\site-packages\requests\api.py", line 50, in request    response = session.request(method=method, url=url, **kwargs)  File "C:\Python27\lib\site-packages\requests\sessions.py", line 468, in request    resp = self.send(prep, **send_kwargs)  File "C:\Python27\lib\site-packages\requests\sessions.py", line 576, in send    r = adapter.send(request, **kwargs)  File "C:\Python27\lib\site-packages\requests\adapters.py", line 433, in send    raise SSLError(e, request=request)requests.exceptions.SSLError: EOF occurred in violation of protocol (_ssl.c:590)

I've searched for a solution and I've tried to fix with this code:

import requestsfrom requests.adapters import HTTPAdapterfrom requests.packages.urllib3.poolmanager import PoolManagerimport sslclass MyAdapter(HTTPAdapter):    def init_poolmanager(self, connections, maxsize, block=False):        self.poolmanager = PoolManager(num_pools=connections,                                       maxsize=maxsize,                                       block=block,                                       ssl_version=ssl.PROTOCOL_TLSv1)s = requests.Session()s.mount('https://', MyAdapter())s.get('https://host/meters/a_serial/power')

But it doesn't work for me cause I get this error:

Traceback (most recent call last):  File "C:/Users/mzilio/PycharmProjects/pwrgtw/test.py", line 16, in <module>    s.get('https://host/meters/a_serial/power')  File "C:\Python27\lib\site-packages\requests\sessions.py", line 480, in get    return self.request('GET', url, **kwargs)  File "C:\Python27\lib\site-packages\requests\sessions.py", line 468, in request    resp = self.send(prep, **send_kwargs)  File "C:\Python27\lib\site-packages\requests\sessions.py", line 576, in send    r = adapter.send(request, **kwargs)  File "C:\Python27\lib\site-packages\requests\adapters.py", line 433, in send    raise SSLError(e, request=request)requests.exceptions.SSLError: EOF occurred in violation of protocol (_ssl.c:590)

I'm stuck on this problem. Could someone help me? Thanks!
