+## Summary:
+- When I configure Telegram Trigger, I got an error message: **Telegram Trigger: Bad Request: bad webhook: An HTTPS URL must be provided for webhook**
+- I search ChatGPT and got solved by this solution:
+- **Steps to Resolve:**
+
+1. **Ensure HTTPS Accessibility:**
+    
+    - Verify that your **n8n** instance is accessible via an HTTPS URL. If you're running **n8n** locally or without HTTPS, Telegram's webhook setup will fail.
+2. **Configure Environment Variables:**
+    
+    - Set the `WEBHOOK_URL` environment variable to your HTTPS URL. For example:
+        
+        ini
+        
+        CopyEdit
+        
+        `WEBHOOK_URL=https://your-domain.com/`
+        
+    - This informs **n8n** to generate webhook URLs using HTTPS.
+
+I added environment variable in Docker Desktop:
+WEBHOOK_URL    https://n8n.cpolar.top
+
+After then to check the webhook URL in Telegram Trigger:
