Can't get local fulfilment to work

I’ve looked through the forum, but sadly nothing seemed to quite match my particular issue.

Hey, I am trying to setup local fulfilment for Google Assistant however according to stack driver all requests failed, cloud fallback works fine, however I don’t know what’s wrong with local fulfilment. Google’s stackdriver shows No message was received before the deadline . I tried debugging using chrome://inspect#devices , however the URL bar shows which doesn’t sound right to me and no errors about local fulfilment or any errors whatsoever Using an mDNS discovery app, i can discover _home-assistant._tcp
