That log is a version/protocol split: the CLI says v2026.5.6 maxProtocol=3, but the gateway expects protocol 4. So the fix is almost certainly “make every OpenClaw binary/service come from the same version, then restart the gateway.”

Paste this into your local agent:

Fix my OpenClaw gateway protocol mismatch.

Symptom:
- `GatewayClientRequestError: protocol mismatch`
- logs show CLI/client `version=2026.5.6`, `minProtocol=3`, `maxProtocol=3`
- gateway reports `expectedProtocol=4` / `minimumProbeProtocol=4`
- platform is macOS/darwin, gateway host is `127.0.0.1:18789`

Goal:
Make the OpenClaw CLI, gateway service, dashboard/UI, and any global/npx install resolve to the same current version, then restart the gateway and verify `openclaw doctor` / `openclaw gateway status` no longer show protocol mismatch.

Rules:
- First run `openclaw --version`, `which openclaw`, `npm root -g`, `npm list -g openclaw --depth=0`, and inspect whether nvm is involved.
- Check for multiple OpenClaw installs or stale launchd service paths, especially old nvm Node paths.
- Do not delete user data or sessions unless you explain why and ask first.
- Prefer updating/reinstalling the OpenClaw package and reinstalling/restarting the macOS gateway service.
- After changes, run `openclaw --version`, `openclaw gateway status`, and `openclaw doctor`.
- If the service still points at an old Node/global package path, uninstall OpenClaw from the old nvm Node version, install it under the intended Node version, then reinstall/restart the gateway service.

- <https://docs.openclaw.ai/gateway/protocol>

If it gets stuck, have it paste back the outputs of openclaw --version, which openclaw, openclaw gateway status, and the first protocol-mismatch log after restart.
