Unable to get local issuer certificate when using requests in python

by

It’s not recommended to use verify = False in your organization’s environments. This is essentially disabling SSL verification.

Sometimes, when you are behind a company proxy, it replaces the certificate chain with the ones of Proxy. Adding the certificates in cacert.pem used by certifi should solve the issue. I had similar issue. Here is what I did, to resolve the issue –

  1. Find the path where cacert.pem is located –

Install certifi, if you don’t have. Command: pip install certifi

import certifi
certifi.where()
C:\\Users\\[UserID]\\AppData\\Local\\Programs\\Python\\Python37-32\\lib\\site-packages\\certifi\\cacert.pem

  1. Open the URL on a browser. Download the chain of certificates from the URL and save as Base64 encoded .cer files.

  2. Now open the cacert.pem in a notepad and just add every downloaded certificate contents (---Begin Certificate--- *** ---End Certificate---) at the end.
