Requests.exceptions.sslerror: eof occurred in violation of protocol (_ssl.c:680)

Question

Problem :

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

On linux I tried with below command:

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

All is going well!

But when I am trying to write the script for the windows in Python 2.7.10 with the Requests 2.8.1 and with below code:

import requests

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

I often face below error:

Traceback (most recent call last):

raise SSLError(e, request=request)

requests.exceptions.SSLError: EOF occurred in violation of protocol (_ssl.c:680)

Answer 1

Below codes worked for me, just make sure that whether these modules are installed or not, if not installed then please install them, below are:

pip install ndg-httpsclient
pip install pyopenssl
pip install pyasn1

It removed the SSLError: EOF occurred in violation of protocol (_ssl.c:690) error.
