Chrome Extension Relay — invalid request frame / stuck on …
Chrome Extension Relay — invalid request frame / stuck on …
Version: OpenClaw 2026.2.22 | macOS (Apple Silicon) | Chrome 145
Issue: Browser Relay extension badge stuck on … and never connects.
Gateway logs show:
invalid handshake
handshakeError: 'invalid request frame'
lastFrameMethod: 'forwardCDPEvent'
origin: chrome-extension://nglingapjinhecnfejdcpihlpneeadjp
What I've tried:
• Reinstalled extension multiple times via openclaw browser extension install + reload unpacked
• Tried ports 18792, 16768, 16765 in extension Options
• Gateway restart
• Extension reload in chrome://extensions
Root cause (diagnosed): Extension connects to ws://127.0.0.1:16765/extension?token=... — WebSocket upgrade succeeds (101) but first frame forwardCDPEvent is rejected. Gateway expects a different frame type first. Port 18792 (default relay port per docs) is never listening.
Question: What port/path should the extension relay be on in 2026.2.22? Is there a config to explicitly start the relay server?
