I have a webserver serving Django through Apache 2.4 with mod_wsgi and Python 2.7 on Ubuntu 14.04. When first setup, outgoing connections from this webserver using the Python library urllib3 were successful. Currently, outgoing connections using urllib3 are possible using the Python command line client, but the Apache server is failing them with Error 0 after hitting it's maximum retries. I am unsure of what recent changes may have caused the issue.
Are there any recommended techniques for diagnosing and addressing Apache's sudden inability to conduct outgoing requests with urllib3?
