Subject: Webhook Trigger Not Receiving Data and Automation Failures After Initial Success

Description:

I have deployed my n8n instance on Railway. I use a webhook trigger node in n8n to receive form submissions from Typeform.

The main issues are:

1. Webhook Trigger Issue
   • The form submits successfully on the front end, and Railway logs show requests reaching my n8n endpoint.
   • In n8n, the execution starts but the webhook trigger node shows an error.
   • The workflow does not receive or display the submitted data in the execution log.
   • Downstream nodes fail because they have no input.
2. Automation Failure After Running Initially
   • When I create a new automation in n8n, it runs correctly at first.
   • After some time (without changes to the workflow), executions start failing.
   • This happens even if the same trigger and data source are used.
   • It suggests either a connection timeout, webhook URL invalidation, or background service suspension in Railway.

Steps to reproduce:

1. Deploy n8n on Railway.
2. Create a workflow starting with a webhook trigger node.
3. Connect Typeform to send submissions to the webhook URL.
4. Submit any entry in Typeform.
5. Observe:
   • Initially, the workflow executes correctly.
   • After some time, the same workflow begins failing at the trigger node, with no data passed to downstream nodes.

Expected behavior:

• The webhook trigger node should consistently capture payloads from Typeform.
• Automations should continue working over time without unexpected execution failures.

Actual behavior:

• Webhook trigger often fails to capture data despite Railway confirming the request reaches the service.
• Workflows that initially run correctly later fail without changes being made.

Environment:

• n8n deployed on Railway
• Webhook trigger node as workflow start
• Typeform submissions as the source of webhook requests

Request:

Please confirm if Railway deployment settings, routing, SSL, or background process handling are causing the webhook connection to break or executions to fail after a period of inactivity.
