Rasa run build unaccessible

Hi the community,

We are trying to implement our rasa data & model on an aws ec2 instance to be reached by our UI. Although address:5005/version is said to be accessible once built, it appears not to be, not even fallbacking onto a 404, neither from browser search nor curl.

This is what we get (and where it stops outputing stuff in the console):

rasa run -m models --enable-api --cors "*" -vv

Any ideas why and/or what is this about ?
