Nginx reverse proxy issue

Rasa Open Source
1

Hello,

I’m not an nginx user, so my error could be basic, but I am looking for some help.

I have a VPS which I have spun up with the sole purpose of hosting a rasa server. Lets call it chat.example.com

I have my normal website, and on one of the page, I want to call the chatbot. I do this using the rasa web widget. Lets call this example.com

If I set the websocket on example.com to http://chat.example.com:5005, the widget works fine.

However, as this will be a production bot in future, I want the call on example.com to be to: https://chat.example.com:5006

(I’m using 5006, as 5005 is being used by rasa).

To this end, I’ve set up nginx using the following:

server {

  listen 5006 ssl;
  server_name chat.example.com; 
 

    ssl_certificate /etc/letsencrypt/live/[REDACTED]/fullchain.pem; # managed by Certbot 
    ssl_certificate_key /etc/letsencrypt/live/[REDACTED]/privkey.pem; # managed by Certbot

 
    location / {
        proxy_pass http://0.0.0.0:5005;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
	proxy_redirect https://0.0.0.0:5006 http://0.0.0.0:5005;
    }

}

However, the calls aren’t making it to rasa server.

When I edit the underlying call to be to http://chat.example.com:5005, it works fine so the server is running correctly. I think the issue is with nginx.

Can anyone help?

as usual - fastest way to solve your own issues us to ask for help in public.

When I altered the port to 5006, I forget to open that in the firewall. And spent the next two hours looking for an error in good code.

The above script seems to be good for what I am trying to do, but if this is wrong approach or if there is something I am missing, I’d love to hear it.
