"[Errno 111] Connection refused" on Pythonanywhere

Question

I am trying to deploy my application on pythonanywhere but I am unable to connect to twitter.

Here is the error that I am getting :-

Traceback (most recent call last):

self.timeout, self.source_address)
File "/usr/lib/python2.7/socket.py", line 571, in create_connection
raise err
IOError: [Errno socket error] [Errno 111] Connection refused

The code I am trying to run is this :-

proxies = {'http': 'http://proxy.server:3128'}
connection = urllib.urlopen(url, proxies=proxies)
data = connection.read()

And I am trying to access the following URL :- 'https://api.twitter.com/1.1/application/rate_limit_status.json'

I have a free account on pythonanywhere and verified that the API is whitelisted and I am using the proxy as described by them here (http://help.pythonanywhere.com/pages/403ForbiddenError).

Copying my comment to a proper answer: getting proxies to work with urllib can be tricky. requests is in general much easier to use, and it pulls proxy settings from environment variables. Definitely recommended!
