Hi,
I am sorry, 
but I am still having some troubles when trying to make the bot available to colleagues:
So, I do the following steps:
- I start the rasa action sever
rasa run actions --port 5056
- I start rasa
rasa run -m models --enable-api --cors “*” --debug
- I authentificate ngrok
- when rasa is up and running I, then I start
ngrok http 5005
- I log in to the Wordpress-Website, open the Insert Header and Footer-Plugin and within the html-code I change the socketUrl to whatever ngrok gives me:
socketUrl: “https://xxxx-xxx-xxx.ngrok.io”
- save the changes and visit the website
However, usually it does not work immediately, meaning that only I can see the bot, but neither of my colleagues can. So I either restart rasa rasa or ngrok or both several times until then suddeny it works. 
basically, I just try to restart without a plan… 
Did I miss something here? Do you have an idea where the problem might come from and what I could do about it?
I see the following error in the terminal:

When it finally is up and running, then it works like a charm… for days and days 
Thanks for helping me out over and over again,

I guess you need to authenticate the ngrok token.
