ssl.CertificateError: hostname 'audioboom.com' doesn't match '*.audioboom.com

This was working on this system. 
This works on Windows 7 with Python 3.2.

audioboom.com should match *.audioboom.com. Python 3.2 is too old and broken in this case. Please upgrade your Python version.

Sorry, my previous argument is wrong - audioboom.com should not match *.audioboom.com. Instead, there are two items in subjectAltName (subject alternative name) of the server's SSL certificate. The hostname matches the second alternative name Python 3.2 should work for audioboom.com. On my PC Python 3.2.6 works fine. Could you run the following script?

import pprint
import socket
import ssl

host = 'audioboom.com'

context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_REQUIRED
context.set_default_verify_paths()

sock = socket.create_connection((host, 443))
ssl_sock = context.wrap_socket(sock, server_hostname=host)
pprint.pprint(ssl_sock.getpeercert())

It should print:

{'OCSP': ('http://gp.symcd.com',),
 'caIssuers': ('http://gp.symcb.com/gp.crt',),
 'crlDistributionPoints': ('http://gp.symcb.com/gp.crl',),
 'issuer': ((('countryName', 'US'),),
            (('organizationName', 'GeoTrust Inc.'),),
            (('commonName', 'RapidSSL SHA256 CA'),)),
 'notAfter': 'Aug 13 23:59:59 2018 GMT',
 'notBefore': 'Jul 18 00:00:00 2016 GMT',
 'serialNumber': '723F3BBDCB7EF6347AD559E7C374A917',
 'subject': ((('commonName', '*.audioboom.com'),),),
 'subjectAltName': (('DNS', '*.audioboom.com'), ('DNS', 'audioboom.com')),
 'version': 3}

Note the subjectAltName line. There are two items. If there's only one, check your OpenSSL settings.

OK I can reproduce this bug on Python 3.2.2. It's Python's bug, which is fixed in 3.2.3 and 2.7.3, please upgrade your Python version.
