1. Symptoms

The `docker-port-allocated` error manifests when Docker fails to bind a host port to a container port. Common error message:

docker: Error response from daemon: driver failed programming external connectivity on endpoint festive_fermi (uuid): (iptables failed: iptables –wait -t nat -A DOCKER -p tcp -d 0.0.0.0/0 –dport 80 -j DNAT –to-destination 172.17.0.2:80 ! -i docker0: iptables: No chain/target/match by that name.

Fix clw-auth-disconnected: Resolve OpenClaw authentication disconnection during sessions

Fri, 04 Oct 2024 00:00:00 +0000

1. Symptoms

The `clw-auth-disconnected` error in OpenClaw manifests during authentication handshakes or active sessions. Clients log:

[ERROR] clw-auth-disconnected: Authentication stream closed unexpectedly (code: 0xA03)


Symptoms include:

- Abrupt session termination after initial auth success.
- Failed API calls returning 503-like responses with auth context.
- Network traces showing TCP RST or FIN-ACK from server post-auth packet.
- Client-side: `ClwAuthHandle` becomes invalid, `clw_auth_status()` returns `CLW_AUTH_DISCONNECTED`.
- High-frequency occurrences under load, e.g., >100 concurrent sessions.
- No data corruption; pure auth-layer disconnect.

Repro steps: Run OpenClaw client against a loaded server, simulate 5-10s latency spikes. Error rate spikes to 40% on unstable networks.

Logs often pair with:

[DEBUG] clw-net: Heartbeat timeout after 3000ms [WARN] clw-auth: Token refresh failed, seq=0xFF
