Webhook occasionally returns status code 499

Questions

Describe the problem/error/question

I have a workflow that starts with a webhook trigger and ends with a respond to webhook node. The respond to webhook node however occasionally returns status code 499 while the execution in n8n doesn’t show any error and the respond to webhook node displays the expected output.
This error doesn’t happen every time the workflow is executed but does happen quite frequently

What is the error message (if any)?

Result in Postman:

Output in n8n shows the expected output like nothing went wrong

Share the output returned by the last node

Contains personal data so I cant share

Information on your n8n setup

  • n8n version: 1.36.1
  • Database (default: SQLite): Default
  • n8n EXECUTIONS_PROCESS setting (default: own, main): Default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): n8n cloud
  • Operating system: Windows

Hi @Erhan_Ozturk

is this a flow that runs a bit longer? So it would be done succesfully but not in time for the client and it gives this sorta timeout?

This is likely related to some changes we made to the reverse-proxy we use in n8n cloud. We are investigating now.

I dont think thats the issue. The execution time for the workflow is always around 2 seconds. Although the executions that show status code 499 in Postman do take a bit longer than the executions that show the proper output
