Rasa NLU with HTTPS?

I have been running Rasa open source chatbots in HTTP website. Now I’m moving to HTTPS. This is my environment

rasa 1.10.11
Botfront webchat 0.11.12
Docker Version 20.10.5
Apache/2.4.29 (Ubuntu)
18.04.1-Ubuntu
Azure cloud VM

So I’m running Rasa in docker container and using Botfront webchat as frontend running in Apache2 webserver. I updated Apache to use HTTPS at chatbot website, but now my bot is not anymore visible. I have understood that I have to somehow introduce certification keys created by Certbot to Rasa?

How to do that?

Hello!

I’m still stuck. I have looked other HTTPS issues but no help, some suggest NGROK but no instructions with Apache.

Anyone?
