This would be much better posted on the github page for the project. I don't have the URL handy, but if you search github for "Python Azure SDK" you'll find it.

Subject: [Python-Dev] Azure event hub network access

I am getting http error 404. I am able to access the site via telnet which eliminates network issues. Here is the code and subsequent errors

    authentication.sign_request(request, httpclient)
