When I request a URL with an expired HTTPS certificate I do not get a meaningful error from requests. Instead it gives me a cascade of "ssl.SSLError: A failure in the SSL library occurred
".
See this example with https://expired.badssl.com/ :
>python

Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> requests.get("https://expired.badssl.com/")

>>>
requests
is 2.24.0 and ssl.OPENSSL_VERSION
says "OpenSSL 1.1.1h 22 Sep 2020". I can not update the packages.
How can I get a meaningful error or error message that tells me that the certificate is expired?
from How to get more details on a requests.exceptions.SSLError?
