Hello Tom,

It should not to be sensitive to import order, but I will investigate better 
also this.

This import is not working and I will investigate why.
It's of course related to the patch but it's a bit strange:

>>> import requests.packages.urllib3.connection
>>> dir(requests.packages.urllib3.connection)
['BaseSSLError', 'ConnectTimeoutError', 'ConnectionError', 'DummyConnection', 
'HTTPConnection', 'HTTPException', 'HTTPSConnection', 'RECENT_DATE', 
'SocketTimeout', 'SystemTimeWarning', 'UnverifiedHTTPSConnection', 
'VerifiedHTTPSConnection', '_HTTPConnection', '__builtins__', '__doc__', 
'__file__', '__name__', '__package__', 'assert_fingerprint', 'connection', 
'datetime', 'match_hostname', 'port_by_scheme', 'resolve_cert_reqs', 
'resolve_ssl_version', 'six', 'socket', 'ssl', 'ssl_wrap_socket', 'sys', 
'warnings']
>>> requests.packages.urllib3.connection.HTTPConnection
<class 'urllib3.connection.HTTPConnection'>

So the form "import <>" is working but not the "from ... import". 

I can't look at this right now, but I will work on it, I hope tomorrow. Feel 
free to open a serious bug against requests, since the purpose of the monkey 
patching is to transparently work.

Of course, any suggestions are appreciated! :)

I tried these and they seem to work.

I'm sorry for the more work you had to do, the monkey patch approach was 
supposed to avoid all of this.

This seems to be related on DNS, can you try to simply resolve the host name?

Kind regards,
