rasa: Fatal error - engineio.server - https://mysite.com is not an accepted origin. after upgrade

Rasa version: Rasa 1.2.2

Rasa X version (if used & relevant):

Python version: Python 3.6.8

Operating system (windows, osx, …): ubuntu server

Issue:

After run pip3 install rasa --upgrade

I started to get the message: engineio.server - https://mysite.com is not an accepted origin.

Now my webchat is broken and I’m stuck !!!

It seems to be related to cors but I tried the command above and still it didn’t work.

rasa run --m models/dialogue --enable-api --debug --endpoints endpoints.yml --credentials credentials.yml --cors ‘*’

Thanks !
