When using urllib2 to open any https link the following error is given:
urllib2.URLError: urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)

Found a workaround by using:
import ssl
ctx = ssl._create_unverified_context()
urllib2.urlopen("https://link", context=ctx)

This works for now, but obviously a proper fix is preferred.
