I run it in a linux mint virtual machine. Rasa version 1.2&1.1.8. I create a simple html with just webchat embed in it.

With command: rasa run --m models/20190807-145638.tar.gz --endpoint endpoints.yml --enable-api --credentials credentials.yml --cors “\*”

It’s a problem of version of engineio and socketio. You should do this after rasa installation:

pip install python-engineio==3.8.1 python-socketio==4.0.3

I used rasa 1.1.8 no problem. Maybe you should try this version.
