n8n Cloud Workspace Offline (503 Error)

Ongoing n8n Cloud Updated October 21, 2026

Quick answer

A 503 'Workspace offline' page means your n8n Cloud instance is down or restarting, often after running out of memory or during an incident. Restart the workspace from the Cloud dashboard and contact support if it doesn't come back.

Most likely fix: Restart the workspace.

Symptoms

The editor URL shows a 503 or 'Workspace offline' page, workflows stop running, and the workspace may stay offline after a plan change.

Why it happens

  • Instance crashed after running out of memory
  • Platform incident or stuck deployment
  • Provisioning issue after a plan upgrade

How to fix it

Try these in order — the most common fix is first.

  1. 1. Restart the workspace

    1. Log in to the n8n Cloud admin dashboard as the workspace owner
    2. Restart the instance and wait a few minutes

  2. 2. Reduce memory pressure

    1. Deactivate the workflow that was running when it crashed
    2. Batch large data with Loop Over Items or upgrade the plan for more memory

  3. 3. Escalate to support

    1. Email n8n support with your workspace name and when it went offline
    2. Post in the n8n community forum Cloud category for visibility
    3. Keep critical workflows exported as JSON so you can run them elsewhere
