SSL certificate verify failed (_ssl.c:600)

Question

Do you know about this error:

urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)

This error occurred on my server when I run my app which is written on python, but when I run this app on local computer for sending requests to that server it works without any error. The python app sent to https request to myhost.com/action. and the web host is working with https. I checked ssl from sslchecker and it seems ssl installed succesfully. here is checker result:

I don't know what I must show here to explain my problem. If you have a question about code or server settings I will try to answer as I can.

** This question isn't duplicate of that one

Answer 1

A new ssl certification checking system is added in python 3, and one way to avoid the error of not passing certification is to nullify this mechanism:

import ssl
ssl._create_default_https_context = ssl._create_unverified_context
