Hi all,
I’m encountering an issue where my Telegram bot messages work perfectly in test workflow mode, but once I switch to live mode the messages just seem to get lost. When toggling the live workflow off and on again, the messages trigger, but otherwise, they don’t appear to reach the workflow.
Below is my workflow configuration for reference:
JSON{ “meta”: { “instanceId”: “0ce372dee332818ef9b4209a4c9f2ca132786baf9121368927561de85b0a293e” }, “nodes”: [ { “parameters”: { “chatId”: “={{ $(‘Telegram Trigger’).item.json.message.from.id }}”, “text”: “={{ $json.output }}”, “additionalFields”: { “appendAttribution”: false } }, “id”: “1c273502-227c-43d9-bb23-e1a5dd1c944d”, “name”: “Respond to Me”, “type”: “n8n-nodes-base.telegram”, “typeVersion”: 1.2, “position”: [ 940, 460 ], “credentials”: { “telegramApi”: { “id”: “wKcsVlh8uu1ckQ51”, “name”: “Telegram account” } } }, { “parameters”: { “updates”: [ “message”, “channel_post” ], “additionalFields”: {} }, “id”: “ef68eec6-47ac-4aab-a0de-2d4b0110b491”, “name”: “Telegram Trigger”, “type”: “n8n-nodes-base.telegramTrigger”, “typeVersion”: 1.1, “position”: [ 460, 460 ], “webhookId”: “2194a6b2-2302-4406-9c8c-207161b7eb22”, “credentials”: { “telegramApi”: { “id”: “wKcsVlh8uu1ckQ51”, “name”: “Telegram account” } } }, { “parameters”: { “promptType”: “define”, “text”: “={{ $json.message.text }}”, “options”: { “systemMessage”: “You are a personal assistant. Here is the current time/date: {{ $now.format(‘DD’)}}” } }, “id”: “7c43adb3-384f-43f3-9ae0-f3572217cd90”, “name”: “Personal Assistant”, “type”: “[@n8n](/u/n8n)/n8n-nodes-langchain.agent”, “typeVersion”: 1.6, “position”: [ 620, 460 ], “retryOnFail”: false } ], “connections”: { “Telegram Trigger”: { “main”: [ [ { “node”: “Personal Assistant”, “type”: “main”, “index”: 0 } ] ] }, “Personal Assistant”: { “main”: [ [ { “node”: “Respond to Me”, “type”: “main”, “index”: 0 } ] ] } }, “pinData”: {} }
Here are some screenshots for further context:
Messages are sent when in test workflow mode or immediately after toggling the live mode on and off, but the automation hangs when fully live.
Additional Setup Information:
- n8n version: Cloud
- Database: Default (SQLite)
- n8n EXECUTIONS_PROCESS setting: Default
- Running n8n via: Cloud
- Operating system: MacOS
Has anyone experienced similar issues or have suggestions to resolve the problem? Thanks in advance!

Below is some guidance on how to troubleshoot this behavior with your Telegram bot in a live workflow.
Likely Cause
When using the test workflow mode, n8n bypasses the usual webhook registration steps (or resets the canvas), which is why everything appears to work. In live mode the Telegram Trigger node relies on the webhook connection being properly registered and maintained. If the webhook isn’t being reset or re-registered correctly when you deploy the live workflow, messages can seem to disappear or “get stuck.”
Troubleshooting Steps
-
Reset the Webhook
As a first step, try disabling your live workflow and then re-enabling it. This forces the webhook to reinitialize. Many users have seen that toggling the live switch kick-starts the webhook registration again. -
Check Webhook URL and HTTPS
If your n8n instance is running behind a reverse proxy you must ensure that:- Your public webhook URL is configured with HTTPS.
- Websocket support is enabled on your reverse proxy.
Although you’re using n8n Cloud (which should take care of this), it’s worth verifying that the public URL for your webhook is correct.
-
Review Your Node Configuration
Ensure that the expression used to extract the Chat ID is correct. For example, verify that={{ $('Telegram Trigger').item.json.message.from.id }}is returning a valid value. Any misconfiguration here could affect message sending when the workflow is live.
Summary
Your issue is consistent with problems where the Telegram Trigger node’s webhook connection isn’t maintained or reinitialized properly in live mode. Disabling and re-enabling the workflow can help reset the connection. Additionally, check that your webhook URL is publicly accessible via HTTPS and—if applicable—your reverse proxy is set up to support websockets.
Give these steps a try and see if they resolve the issue. If you run into further problems, you might want to check your n8n logs for any error messages related to webhook registration or network issues.

This behavior can occur because Telegram only allows a single registered webhook per bot. When you use both testing and production URLs, Telegram overwrites the webhook URL each time you switch modes. As a result, only one (either the testing or the production) receives events, and when neither is active in the expected way, messages can appear to be lost.
How to Resolve
-
Disable Test Workflows During Production:
When your workflow is live (using the production webhook), disable the test workflow. This ensures that Telegram sends events only to the production webhook. -
Separate Bots for Testing vs. Production:
If you need to test without impacting production, consider creating a separate Telegram bot for your testing environment. This way, each bot can have its own distinct webhook URL and won’t conflict.
For more details, see the common issues documentation for the Telegram node in n8n.
