If this has only started happening recently, then the cause is more
likely to be related to PyPI switching over to requiring TLS v1.2+ for
all client access: a sufficiently outdated man-in-the-middle SSL/TLS
proxy may not be able to meet PyPI's client security requirements. See
https://pyfound.blogspot.com.au/2017/01/time-to-upgrade-your-python-tls-v12.html
for more details.

(If that's the problem, it would affect all versions of Python equally though).

Nick.
