Telegram Trigger - Bad Request

Questions
1

Hi,
yes, there are some good explanations to that topic. But for a full understanding I still need some more information - just to get deeper.

Describe the problem/error/question

Am I right, that Telegram Trigger Node in n8n only works only with a public URL?
If yes, may be DDNS a solution?
How can I get the n8n-generated URL as displayed in https://github.com/n8n-io/n8n/issues/12967?
What are the differences to Node RED (sorry), where a telegram-receiver-Node is available? As far as I remember, this node works locally.

What is the error message (if any)?

Telegram Trigger: Bad Request: bad webhook: Webhook can be set up only on ports 80, 88, 443 or 8443

Hi,

you would need to use a tunnel service like ngrok, cloudflare, etc (even n8n has a --tunnel option) as you most likely don’t have a direct routable ip address.

you map the tunnel (lets say: https://whatever-name to localhost 5678

after that you set the WEBHOOK_URL=https://whatever-name/

as it has been requested many times: here’s a solution N8n Desktop custom Webhook url ngrok - #4 by Jon
(but you need to change the port accordingly)

reg,
J.
