RASA problem connecting to Telegram

Rasa Open Source
21

Hi Guys.

I´m trying to connect my bot directly to my IP (ngrok whats ok but i need connect directly to my server) on Telegram and Twilio WhatsApps.

  1. Telegram:

The problem i think is the next: Telegram use https and my server EC2 only have HTTP, if i search the site online (http://54.80.233.189:8443/) is working and say Hello from Rasa: 1.3.9, and work to in RASA X (with HTTP).

If i send a message from Telegram, Rasa say "httptools.parser.errors.HttpParserInvalidMethodError: invalid HTTP method " so Telegram connect to my server … is must be a HTTPS incompatibily. The problem is i try to start with port 443, 80 or 88 the system denied me. Port 8433 work but i can open html port in my ec2 console.

mycredentials.yml

#telegram:

access_token: “…”

verify: “bot”

webhook_url: “https://54.80.233.189:8433/webhooks/telegram/webhook”

  1. Twilio when a message arrive said me

Method not allowed error 405

any help?

I believe you will want to setup ngrok on this machine or nginx or something to get SSL going from your ec2 instance and this should work.

You basically need to replicate what you did locally and ngrok basically sets up SSL for you which would need to be done on this ec2 instance.

@Nicanor

Did you solve this?

I am also facing same issue .My rasa server is running via ngrok but https://f9a8b004.ngrok.io/ gives hello from rasa 1.9.0 but https://f9a8b004.ngrok.io/webhooks/telegram/webhook will say url not found

25

using rasa run command you will get port number and try to forward it into ngrok
