Webhook cut off after 100 s on n8n Cloud (Cloudflare timeout) — what’s the fix?

Questions

Hi everyone,

  • Setup: n8n Cloud (Team plan)

  • Context: A webhook triggers a workflow that takes about 3 minutes.

  • Issue: After exactly 100 seconds, Cloudflare closes the connection and I receive a 524/504 timeout error.

I haven’t found how to get past this 100-second limit or prevent the timeout.

Question: What is the recommended solution to this problem on n8n Cloud?

Thanks in advance for any advice or experience you can share!

Hi,

Cloudflare sits in front of all n8n Cloud webhooks and enforces a ~100-second timeout. If your workflow takes longer than that, the connection will be dropped with a 524/504, and this can’t be changed on n8n Cloud.

The workaround is to respond quickly and let the heavy lifting happen in the background:

  • Use a Response to Webhook node to return 200 OK right away.

  • Keep processing your workflow asynchronously, and if you need to deliver results later, either trigger a second webhook or let the client poll for completion.

The only other option would be self-hosting n8n, where you can control the timeout yourself.

Hope that helps! Let me know if you need an example setup and I can share more details.

another options outside @AlvLeoAI answer is considering selfhost. This way, you can configure your own timeout settings and aren’t limited by Cloudflare’s restrictions.
