The short answer

Resolve common OpenClaw issues by verifying Node.js 24.16+ or 26.1+, running openclaw doctor to inspect environment health, confirming port 18789 is available for the Gateway daemon, and testing model credentials directly. If messaging channels fail to pair, restart the Gateway process after saving token configurations and verify channel plugins are active.

Most Common Issues and Fixes

  • Install fails or Node version error: Ensure Node 24.16+ or 26.1+ is installed. Re-run the official install script.
  • Gateway will not start: Run openclaw gateway status and openclaw doctor. Verify port 18789 is free. Reinstall the daemon if needed.
  • Model authentication fails: Re-run onboarding or manually verify the API key / Claude Code / Codex login. Test with a simple completion.
  • Channel not connecting (Telegram, WhatsApp): Double-check bot tokens and pairing codes. Restart the Gateway after configuration changes.
  • Agent ignores tools or skills: Reload or restart the Gateway after installing skills. Confirm the skill is enabled in active configuration.
  • High CPU or memory usage: Check for runaway scheduled jobs. Limit concurrent sessions and review tool permissions.

Keep the project updated. Most issues reported in late 2026 are resolved by updating to the latest stable release and re-running the doctor command.
