Quanta Magazine Recipe

Quanta magazine recipe since few weeks cannot download the articles .. it gives me small Epub file with the following message:

Failed feed: Articles
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1123)>

any idea about the fix.

P.S I downloaded the last recipes from GitHub but no fix .. is it a python problem with certificates ?!
