ssl error using urllib2

On Ubuntu 14.04.5 LTS with python 2.7.5-5ubuntu3 and libpython2.7-stdlib 2.7.6-8ubuntu0.3, using this little example program:

#!/usr/bin/python

import urllib2

USER_AGENT = 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.101 Safari/537.36'

defaultHeaders = {'User-Agent':USER_AGENT,
                 'Accept':"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
                 'Accept-Encoding':'gzip,deflate,sdch',
                 'Accept-Language':'en-US,en;q=0.8'}

url = "https://ga.video.cdn.pbs.org/videos/ask-old-house/dcf0b26c-f7d1-4b1f-b1cf-2e521aa5e796/1000010577/hd-mezzanine-16x9/zq3zp3pg_ask1524-cove-16x9-hls-192-2500k.m3u8"
req = urllib2.Request(url.encode('utf-8'), None, defaultHeaders)

response = urllib2.urlopen(req, timeout=30)

I get this result:

$ python /tmp/urllib2-error.py

    response = urllib2.urlopen(req, timeout=30)
