Python urllib.request.urlopen() returning error 10061?

I'm trying to download the HTML of a page (http://www.google.com in this case) but I'm getting back an error. Here is my interactive prompt session:

During handling of the above exception, another exception occurred:

My best guess is that my network's firewall is blocking the connection (most/all ports other than 80 are blocked). I don't see why, though; doesn't Python connect on port 80? Does anyone know what is happening?

The error comes from operating system level and is not related to Python. It would be same with any programming language.

Contact your network administration to see what's the matter unless you can resolve firewall issues yourself. If you need a HTTP proxy then you can configure one for urllib.

urllib takes the proxy settings from Internet Explorer, which is usually under Tools->Internet Options->Connections->Lan Settings

If you have a proxy, make sure it's correct in IE, or set it when using urllib. If you don't use a proxy to browse, make sure that the proxy settings in IE are empty.

I was struggling with this issue few hours until I realized that a 3rd party app I once installed changed the setting in IE, while i was surfing happily in Firefox without a proxy.

Another solution is in the this link which shows how to force urllib to ignore IE's proxy settings
