pipenv lock .... Timing out

See original GitHub issue
I had pipenv working fine then my mac crashed and when i started terminal session again the lock file was missing and pipenv run ... did not work
Tried pipenv lock and over a dozen tries got time out error each time as below
=== Update 10th Jan This problem occurs intermittently. I uninstalled a few libraries from the pip file, installed one and pipenv lock now works on my Mac … deployed the changes to AWS Ubuntu and now get the same timeout error on the Pipfile that works on my mac … see comments END UDPATE ====
Describe your environment

OS Type: Mac
Python version: 2.7.10
Pipenv version: 8.2.7
Expected result

Successful lock file generated
Actual result

Time out error
