After you've updated the proxy settings, if your proxy is running on a separate machine than your VirtualCoach you'll need to add a line to the proxy settings for the VirtualCoach to be able to use your new setup, edit:
and add an entry to the
proxy section in the same format as the local entry e.g.
"<name>" : "http://<ip>:8000"
then when you launch the virtual coach tell it to use this new custom backend setup:
vc = VirtualCoach(environment='<name>')
and you should be good to go.
