How to find emulated hue in google home

Hi, I followed the instructions for emulated hue but the google home doesn’t find it.
Last step for me was sudo setcap 'cap_net_bind_service=+ep' /usr/bin/python3.5
Running hassbian on a raspberry pi V3
http://:80/description.xml Do work.
http:///api/pi/lights also works.
Do I need the Jason for something?
I have a original hue hub and don’t know if it’s giving me interference.
When I pull the plug from it, google home finds nothing.
In the google home app I go to home control>Add device> choose Philips hue . It asks to login and after login it begins to check and find nothing.
What could be the problem?
