Gateway won't start: 'refusing to bind ... without auth'

Fix gateway startup failures when binding to LAN/tailnet without token/password auth configured.

By CoClaw Team •

Symptoms

  • Gateway immediately exits and logs show:
    • refusing to bind gateway to <host>:18789 without auth (...)
  • openclaw gateway status shows the service restarting/crashing.

Cause

When the gateway binds to a non-loopback interface (LAN/tailnet/custom), OpenClaw requires auth to be configured before it listens on that network path. Treat the exact token/password config shape as version-specific and confirm it against the current gateway auth/configuration guide for your installed version.

Fix

1) Set gateway auth through the current config guide

Use token or password auth as documented for your installed version:

Then restart the gateway. Do not disable auth or expose a naked LAN/tailnet dashboard just to make the bind succeed.

2) Or bind only to loopback (local-only)

If you do not need LAN access, bind to loopback (127.0.0.1) and use SSH tunnel / local access.

Verify

  • openclaw gateway status shows running.
  • Use openclaw dashboard for a fresh tokenized browser entrypoint when auth is required.
  • The Control UI stays connected on the intended loopback/tunnel/LAN route.
