TL;DR · WeSearch summary

The author experienced a frustrating issue with their Telegram bot, which failed to respond due to a misunderstanding of webhooks. After troubleshooting, they discovered that the problem stemmed from conflicting URL registrations between n8n and their Cloudflare tunnel. Ultimately, they implemented a startup script to ensure the correct URL was used, leading to a successful resolution of the issue.

Key facts

▪The author was building a Telegram bot for trading but encountered silent failures when sending commands.
▪The issue arose from n8n automatically registering a temporary tunnel URL, overriding the intended Cloudflare URL.
▪After several unsuccessful attempts to fix the problem, the author created a startup script that ensured the correct URL was registered.

Then One Broke My Agent. #ai #agents #python #beginners One day. Same problem. No error messages. Just silence. My Telegram bot wasn't responding. I'd send it a command — "analyze AAPL" — and nothing came back. I'd check n8n. Everything looked fine. The workflow was active. The nodes were connected. Nothing was broken, as far as I could tell.
