How can I extend the Respond to Webhook timeout for Wait Node delays over 64 seconds in n8n?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I have an n8n workflow that starts with a webhook receiving a request and then posts this request to an external service. In my workflow, I use a Wait Node to pause for about 70 seconds before receiving a reply via another webhook. I then use an HTTP Node with $execution.resumeUrl to resume the Wait Node and send the reply back to the initial request.

I noticed that when the Wait Node delay is set to more than 64 seconds, the response never reaches the initial webhook, and it always times out. I created a simplified version of the workflow for debugging, confirming that any wait time greater than 64 seconds leads to a timeout on the initial request.

Is there a way to override this 64-second limit? Can I adjust an environment value or configuration to extend the timeout?

To test this workflow, I use a time query parameter.

n8n setup details:

n8n version: 1.79.3
Database (default: SQLite): Postgres
n8n EXECUTIONS_PROCESS setting (default: own, main): queue
Running n8n via (Docker, npm, n8n cloud, desktop app): docker
OS: Debian 12

BASH
# Example command to run n8n
docker run -it --rm --name n8n \
  -p 5678:5678 \
  n8n/n8n

The behavior you’re experiencing is expected based on how n8n handles wait times: when a wait is less than about 65 seconds, the process continues to run (and the incoming webhook connection stays open), but for longer waits the execution data is offloaded to the database and the connection isn’t held open. This means that if the wait is longer than roughly 64 seconds, the initial webhook request will time out because its response isn’t sent immediately.

There isn’t an environment variable or configuration setting to extend the open connection timeout for the initial webhook beyond this limit. The design is intended to prevent processes from holding connections open for extended periods.

Workarounds to consider:

Respond Immediately: Instead of waiting before replying to the webhook, you might rework the workflow to respond immediately to the incoming webhook (using, for example, the “Respond Immediately” option or a Respond to Webhook node) and then continue processing asynchronously.
Split the Workflow: Separate the external service call and subsequent reply handling into a separate workflow that’s triggered once the external reply is received. This way, the initial webhook isn’t waiting for the long delay.

Using these approaches ensures that the initial HTTP connection does not exceed the timeframe n8n is designed to keep it open.

If your use case absolutely requires a long delay before sending a response back to the original request, you’ll need to modify the workflow design so that the webhook immediately acknowledges the request and then handles the later processing in a separate process.
