Fail to load webchat bot on webpage using ngrok

Rasa Open Source
12

Hi,
I am sorry, :expressionless: but I am still having some troubles when trying to make the bot available to colleagues:
So, I do the following steps:

  1. I start the rasa action sever rasa run actions --port 5056
  2. I start rasa rasa run -m models --enable-api --cors “*” --debug
  3. I authentificate ngrok
  4. when rasa is up and running I, then I start ngrok http 5005
  5. 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”
  6. 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. :woman_shrugging: basically, I just try to restart without a plan… :confused:

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 :slightly_smiling_face:

Thanks for helping me out over and over again, :blush: ciao
