Hi @Nguyen_Duc_Hoan, welcome to the community!

n8n’s trigger nodes use webhooks under the hood and it appears Telegram rejects non-https URLs.

So you’d want to make sure your n8n instance is available under a public https URL here. If you’re using a reverse proxy to handle SSL/TLS termination you might need to set the WEBHOOK_URL environment variable to share the correct URL with n8n.
