OpenClaw Gateway Crash Loop Fix

Fixed OpenClaw gateway crash loop caused by missing controlUi.allowedOrigins configuration. The gateway was set to bind: "lan" which added a Tailscale interface (100.119.174.58) as a non-loopback address, triggering OpenClaw's security check that requires explicit origin allowlisting for non-loopback Control UI access.

Error: non-loopback Control UI requires gateway.controlUi.allowedOrigins (set explicit origins), or set gateway.controlUi.dangerouslyAllowHostHeaderOriginFallback=true

Implemented fix by editing /home/nicholai/.openclaw/openclaw.json to add controlUi section with allowedOrigins array containing:

  • Loopback addresses: http://localhost:18789, http://127.0.0.1:18789
  • Local network: http://10.0.0.189:18789
  • Tailscale interface: http://100.119.174.58:18789
  • Hostname: http://archlinux:18789

The controlUi block was inserted between auth and tailscale sections within the gateway config object. Service restart verified via systemctl --user restart openclaw-gateway.service with status and journal log inspection.
