Summary

Problem Description

When the Feishu WebSocket connection drops (e.g., due to Feishu server maintenance or network glitch), the Lark SDK enters a **permanent reconnect loop** with exponential backoff. The gateway process stays alive but becomes completely unresponsive — the Feishu bot goes offline and messages can neither be sent nor received. [info] [ws] unable to connect to the server after trying 890 times ← after ~24 hours

Steps to reproduce

Key observations:

  • The retry counter never resets or caps — it grows indefinitely
  • The reconnect interval grows to ~100s but never gives up
  • Feishu marks the bot as offline after prolonged disconnect
  • The openclaw channels status --probe still reports "works" even while the bot is effectively unreachable
  • Only openclaw gateway restart breaks the loop and restores connectivity

Environment

  • OpenClaw version: (2026.3.13, via npm)
  • Node.js: v22.22.1
  • OS: Linux (WSL2)
  • Feishu channel mode: WebSocket (long connection)
  • Deployment: local desktop, systemd-managed gateway

Expected behavior

Expected Behavior

According to the docs, WebSocket reconnection should use "exponential backoff with a max of 3 retries and 30s interval." In practice:

  1. The retry count has no upper limit (counter goes to 890+)
  2. There is no mechanism to force a fresh connection after many failures
  3. No watchdog or health-check triggers recovery without manual intervention

Proposed Fix

Add a watchdog mechanism at the OpenClaw gateway level:

  1. Track consecutive WebSocket reconnection failures per channel
  2. After N failures (e.g., 10–20), automatically trigger a channel re-auth (openclaw channels login) or full WebSocket session reset
  3. Consider adding a config option like channels.feishu.reconnectMaxAttempts to let users tune this behavior
  4. Alternatively, add a periodic health-check that detects "connected but non-functional" state and self-heals

Actual behavior

he retry counter never resets or caps — it grows indefinitely

  • The reconnect interval grows to ~100s but never gives up
  • Feishu marks the bot as offline after prolonged disconnect
  • The openclaw channels status --probe still reports "works" even while the bot is effectively unreachable
  • Only openclaw gateway restart breaks the loop and restores connectivity
