Telegram Trigger in Self-Hosted n8n Fails to Retrieve Messages via Cloudflare Tunnel

Hi everyone!

I’m running a self-hosted n8n instance on an old Mac Mini and recently exposed it using Cloudflare/Zero Trust tunnels following a comprehensive guide by @Gavien. The instance appears to be listening for events (as shown in the UI), yet my Telegram trigger never fetches messages – and I suspect other webhook triggers (like Trello or Slack) might encounter the same issue.

I’m not extremely technical, but I’m learning by managing my n8n instance. I’d greatly appreciate any tips or troubleshooting steps to help resolve this issue.

Below is my configuration:

• n8n version: 1.78.1
• Database: default
• n8n EXECUTIONS_PROCESS setting: default
• Running n8n via Docker-Compose & Cloudflare/Zero Trust
• Operating system: MacOS
