[Outbound Connection/DNS Error] n8n Space failing to reach external APIs (Facebook/Telegram)

TeleBridge is a lightweight Vercel proxy that solves Telegram API access/banning issues by routing all Telegram traffic through a public Vercel endpoint.

Use this as the Telegram Credential Base URL in n8n:

https://tele-bridge-cyan.vercel.app

Contribute to expher510/TeleBridge development by creating an account on GitHub.

Do not add a trailing slash.

After updating the credential:

1. Save the Telegram credential.

2. Deactivate the workflow if it is already active.

3. Activate the workflow again.

4. n8n will automatically register the Telegram webhook through TeleBridge.

5. All Telegram nodes should then work normally, including triggers, message actions, callback actions, chat actions, and file actions.
