HTTP Error 502: Parent proxy unreachable

I have done proxy settings using CNTLM and also have a script(google.py) to check proxy setting are working or not 

import urllib.request
proxy_support = urllib.request.ProxyHandler({"http":"http://localhost:3128"})
opener = urllib.request.build_opener(proxy_support)
urllib.request.install_opener(opener)
html = urllib.request.urlopen("http://www.google.com").read()
print(html)

when i run the script I'm getting following errors

C:\Users\asj5cob\Desktop>py -3.4 google.py
Traceback (most recent call last):
  File "google.py", line 5, in <module>
    html = urllib.request.urlopen("http://www.google.com").read()
  File "C:\Python34\lib\urllib\request.py", line 161, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Python34\lib\urllib\request.py", line 470, in open
    response = meth(req, response)

    return self._call_chain(*args)

    result = func(*args)

    raise HTTPError(req.full_url, code, msg, hdrs, fp)

Did you start CNTLM by executing in your administrator cmd window?

net start cntlm
