Webhook stops receiving data in OpenAI workflow (only works again after recreating the webhook)

Hi everyone!
I’m building a workflow in n8n that uses OpenAI to handle automated chat responses. The workflow runs fine most of the time, but occasionally the webhook just stops receiving new requests — it doesn’t respond to new messages anymore.

If I recreate the webhook (or duplicate the node and update the URL), everything starts working again.

Has anyone experienced something similar?
I’d love to understand what might be causing this and whether there’s a way to keep the webhook stable without recreating it every time.

Thanks in advance for any insights! :folded_hands:
