Telegram Trigger on Docker Localhost: Bad Request / HTTPS Webhook Error

[yunus_emre1]

Hi everyone,

I’m running n8n via Docker on my local machine using localhost:5678. When I try to use the Telegram Trigger, I encounter the following issues:

1. When executing the workflow:

Bad request - please check your parameters

2. When activating the workflow:

Bad Request: bad webhook: An HTTPS URL must be provided for webhook

I understand that Telegram requires a public HTTPS URL for webhooks, but I’m running n8n locally via Docker. Could someone advise on the best way to make Telegram Trigger work in a local Docker setup?

Thanks in advance!

In order to register a webhook, Telegram requires the webhook to be HTTPS instead of HTTP. You can use this to get yourself started:

Make n8n Public — Free Production Setup with Docker + Ngrok (No Domain, No Cost!)

Hey @yunus_emre1 , if you can share the ss of the telegram node and json payload if any, also use ngrok for webhook triggers as it will not work with local host

yes exactly what i said

I have a question. in this video (5:14) , He added host path(n8n-data) but I can’t see my n8n-data file.
Do I need to create new file ?

The reason they have it and you don’t is the difference in the initial configuration. They had their bind mount configured to store n8n_data in the home folder, while yours is probably somewhere else.
