Question: Why does the “GatewayRequestError: chat.history unavailable during gateway startup” error occur in OpenClaw v2026.4.11?

Answer:

This error occurs when the chat.history RPC call is being made before the OpenClaw gateway has fully completed its initialization process. The issue is specifically related to the gateway startup sequence in recent OpenClaw versions.

Root Cause

After upgrading to version 2026.4.5 and later (including your v2026.4.11), the gateway startup time increased significantly due to provider validation during the models.list initialization. The gateway process itself starts quickly, but certain WebSocket RPC calls like chat.history can take 30+ seconds to respond during startup, making them temporarily unavailable.

Why This Happens

During gateway startup, OpenClaw performs several initialization tasks:

  1. Provider Validation: When you have multiple AI model providers configured (e.g., 9 providers with 50+ models), the system validates each provider at startup rather than lazily loading them on first use

  2. Service Initialization Delay: In Docker environments, the gateway can take approximately 40 seconds to initialize, and you should not send requests until the logs show “[gateway] listening on :3001”

  3. Race Condition: If the web UI or client attempts to fetch chat history before the gateway’s WebSocket handlers are fully ready, you’ll receive this “unavailable during gateway startup” error

Solutions

Immediate Fix:

  1. Wait for Full Startup: Do not send requests until the logs show the gateway is listening on its port. Monitor the logs with: 
    openclaw logs --follow

    Wait for the message indicating the gateway is ready before accessing the dashboard

  2. Run Doctor Command: Run openclaw doctor --fix to automatically resolve common configuration issues: 
    openclaw doctor --fix
openclaw gateway restart
  3. Increase Timeout: If the default 60-second timeout is not enough, you can increase it in your configuration

Long-term Solutions:

  1. Reduce Provider Count: If you have many model providers configured, consider removing unused ones to speed up startup validation

  2. Check for Configuration Issues: The in-session chat history is temporary and gets cleared when you restart the Gateway. Ensure your workspace files are properly configured

  3. Monitor Startup Sequence: The logs will show when each component becomes available. The typical sequence is:

    • Gateway process starts
    • Plugins load
    • Models list validates (this is the slow part)
    • WebSocket handlers become ready
    • Chat history becomes accessible

Prevention Tips

Run openclaw doctor once a week even when the system is running normally to catch potential issues early, and keep OpenClaw updated with npm update -g openclaw. Also, monitor Gateway memory usage as long-running Gateways may develop memory leaks, and restarting weekly is recommended.

This is a known behavior in recent OpenClaw versions where the startup sequence has become more thorough but slower, particularly with multiple model providers configured. The error is temporary and resolves once the gateway fully initializes.
