OpenClaw remote node gets ECONNREFUSED over Tailscale: gateway status shows Bind: loopback

💡 "Connection refused" from another machine usually means the server listens on loopback only; check the bind address before the network.
发生场景
Source(s): https://www.moltbook.com/post/9b4c63d8-2855-4846-8c79-697768553dd5 Status: reported working by source, not reproduced by us (author's follow-up reply: Linux nodes fixed).
问题
The remote node can't connect, or exits immediately with connection refused, while the gateway looks healthy on its own host.
报错原文（已脱敏/规范化）
Node: ECONNREFUSED Gateway status: Bind: loopback
适用环境
Clawdbot (now OpenClaw) gateway on one machine (the author used clawdbot gateway commands), node on another, connected over a Tailscale tailnet, Linux (Jan 2026 report).
如何确认是这个问题
Gateway status shows Bind: loopback while the node runs on a different machine.
不是这个问题时 / 边界
Windows nodes: the author says Windows pairing was still flaky after these fixes and remained unsolved.
根因
Two misconfigurations. The gateway listened only on 127.0.0.1, so other machines couldn't reach it. The node service was also hardcoded to connect to 127.0.0.1 instead of the gateway host's tailnet address.
占位变量
<gateway_tailnet_ip>: the gateway host's Tailscale address.
修复步骤
- In the gateway config set
gateway.bind: "tailnet"and restart → expect: (our inference) status no longer shows loopback. - Point the node's gateway URL at the gateway's tailnet address (
<gateway_tailnet_ip>), not 127.0.0.1 → expect: the node stays connected. - Also from the same post: if the new gateway can't bind ("port already in use", health check 1006), kill the stuck process and run a single instance under systemd. Don't run a manual CLI gateway next to the service.
如何验证
(our inference) After the change and a gateway restart, ss -ltnp shows the port listening on the tailnet address.
试过没用的办法
Not listed. (our inference: restarting doesn't help while bind is still loopback.)
风险提示
(our inference) Binding to the tailnet interface is safer than binding to all interfaces. Don't expose the gateway port to the public internet.
