Rasa docker nginx revers proxy webchat issue

I try to get Rasa working with nginx reverse proxy and with webchat as frontend. I can only get website working, but no chatbot there
http://vetbot6.westeurope.cloudapp.azure.com:443/

I start my Rasa in container

docker run --name=amva --user 1003 -d -v $(pwd):/app -p “5010:5005” rasa/rasa:1.10.11-full run -m models --enable-api --cors “*” --debug

we can see docker ports here

paulii@vetbot-v6-test:~$ docker ps -a
