N8n unregistering webhooks randomly?

Questions
1

Describe the problem/error/question:
It just randomly unregistered the webhook? I’m not sure what happened but it was working fine, then all of a sudden now the requests from Zendesk aren’t triggering anything.

What is the error message (if any)?
Received request for unknown webhook: The requested webhook “fbded707-00fe-4def-9d82-5dad6d6764c9/webhook” is not registered.

  1. If you recently restarted n8n, reactivate your workflows.
  2. I would check the credentials as well..
    Hope it hepls :slight_smile: and get fixed.

This is exactly what happens in my case. The webhook was already in production, but if I restart the server, when n8n starts up again (with the workflow enabled), it seems that something unregisters the webhook. In the logs, I see: “Received request for unknown webhook…”

After that, I deactivate and reactivate the workflow, and it works again.

Is this normal and expected behavior?

Hey, this is what happens for me everytime. I’ve since quit using n8n in our workflow since it’s not meeting our technical standards with this problem imposed, and I’ve already explored other options!

Thank you for your help!
