Issue
I am getting the following error from gunicorn when I try to bind on port 443:
Retrying in 1 second.
Retrying in 1 second.
Retrying in 1 second.
Retrying in 1 second.
Retrying in 1 second.
Can't connect to ('0.0.0.0',443)
or
Can't connect to ('',443)
Solution
Ports < 1024 are privileged ports. Give access to process that is binding on that port:
setcap CAP_NET_BIND_SERVICE=+eip /usr/bin/python3.6
