The problem in my case was that I needed to add environment variables for http_proxy and https_proxy.

E.g.,

http_proxy=http://your_proxy:your_port
https_proxy=https://your_proxy:your_port

To set these environment variables in Windows, see the answers to this question.

It most likely means the hostname can t be resolved   import socket socket getaddrinfo  localhost   8080    If it doesn t work there  it s not going to work in the Bottle example   You can try  127 0 0 1  instead of  localhost  in case that s the problem
