Telegram and WhatsApp conection problems

Questions
1

lI’m having issues with my WhatsApp and Telegram connections to n8n. These errors appear as soon as I activate the nodes. I connected both using the conventional method, but they won’t start (I created an app in Meta for Developers because Evolution API hasn’t been working since its last update). My n8n instance is hosted on a VPS (Ubuntu), and I’m using Portainer to manage the containers.

Can you share a screenshot of the error you are facing?

The problem is almost always that the apps cannot reach your n8n instance. Start by checking your firewall and network settings

  1. Your n8n must be reachable from the internet. WhatsApp/Telegram need to send messages to it.
  2. Open port 5678 on your VPS firewall.
  3. Use a domain name, not just an IP address, in your webhook settings.
  4. Set the Telegram webhook manually using a curl command.
  5. In Meta’s Developer Portal, double-check that the webhook is enabled and the URL is correct.
  6. In Portainer, verify the n8n container’s ports are mapped correctly (5678:5678).
  7. Temporarily disable Cloudflare proxy (if you use it), as it often blocks webhooks.

This should help
