Error 10060 Failing to Connect

I get the following error message while trying to download instruments in python:

Error 10060 connecting to ec2-18-210-113-195.compute-1.amazonaws.com:27939. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
