Production Webhook URL returning 404 / CORS Error

Questions
1

Hello n8n support team,
I need help with my cloud workflow. My production webhook URL seems to be returning a 404 error, which is causing a CORS error when I try to submit a form from my website.
My n8n instance URL: https://iondubin.app.n8n.cloud/
The workflow ID is: K56CrXcYi3ZYf5ER
The Production Webhook URL is: https://iondubin.app.n8n.cloud/webhook/9b897af0-09e7-4135-a91a-61a41f90c952
I have already performed the following troubleshooting steps:

  • Confirmed the workflow is set to “Active”.
  • Tried deactivating and reactivating the workflow multiple times.
  • Confirmed the webhook node is set to the POST method.
  • My website form is correctly pointing to the Production URL.
  • The browser’s developer console shows a “net::ERR_ABORTED 404 (Not Found)” error for the webhook URL.
    Could you please investigate on your end why my active workflow’s production webhook is returning a 404 error?
    Thank you for your help.

Hey, could you try this:

  • activate workflow
  • move any node a little
  • Save
  • try the webhook again?
