Why Did OpenClaw Stop Replying in a Group Chat?

If OpenClaw suddenly goes silent in a group chat on Discord, Slack, or Microsoft Teams, several factors could be at play. This troubleshooting guide covers every common cause and its solution.

Cause 1: Mention or Trigger Not Detected

In group chats, OpenClaw typically only responds when directly addressed:

# config.yaml — group chat settings
group_chat:
  respond_to:
    - direct_mention: true      # @OpenClaw
    - reply_thread: true        # Replies in existing threads
    - keyword_trigger: true     # Custom trigger words
    - all_messages: false       # Never set true in busy channels
  trigger_keywords:
    - "hey claw"
    - "openclaw"
  mention_format: auto          # auto-detects platform format

Common issues:

• The bot's display name changed, breaking mention detection
• Platform API updated its mention format
• Trigger keywords have typos or wrong casing

# Test mention detection
openclaw integration test --platform discord --channel general --check mentions

# View recent missed messages
openclaw logs --filter "group_chat" --filter "ignored" --last 20

Cause 2: Rate Limiting

Group chats generate high message volumes that can trigger rate limits:

# Check rate limit status
openclaw status --rate-limits

# Output:
# Platform API (Discord): 4/5 requests per second (⚠️ near limit)
# Model API (OpenAI):     55/60 requests per minute (⚠️ near limit)
# Cooldown active:        Yes, 12 seconds remaining

Solution: Configure rate limiting behavior:

group_chat:
  rate_limit:
    max_responses_per_minute: 10
    cooldown_seconds: 5
    queue_overflow: drop        # drop, queue, or summarize
    priority_users:             # These users bypass cooldown
      - "admin_user_id"

Cause 3: Context Window Exhaustion

Busy group chats can fill the context window quickly:

# Check context usage
openclaw memory stats --channel discord:general

# Output:
# Messages tracked:  2,847 (last 24h)
# Context usage:     126,000 / 128,000 tokens (98%%)
# Status:            SATURATED — new messages being dropped

Solution:

group_chat:
  context:
    max_history_messages: 50     # Reduce from default 200
    summarize_after: 30          # Summarize older messages
    ignore_bot_messages: true    # Don't track other bots
    relevant_window: 10          # Only use last 10 for responses

Cause 4: Platform Connection Lost

The WebSocket or API connection to the chat platform may have dropped:

# Check connection status
openclaw integration status discord

# Output:
# Platform:     Discord
# Status:       ❌ Disconnected
# Last active:  2024-06-18 14:23:00 UTC
# Reason:       WebSocket closed (code 1006)
# Auto-reconnect: Attempting (3/5)

# Force reconnect
openclaw integration reconnect discord

# Check all integrations
openclaw integration status --all

Cause 5: Permission Changes

A server admin may have modified bot permissions:

# Verify bot permissions on the platform
openclaw integration check-permissions discord

# Output:
# ✅ Read messages
# ✅ Send messages
# ❌ Read message history (REVOKED)
# ✅ Add reactions
# ⚠️ Manage threads (limited)

Solution: Ask a server admin to restore the required permissions, or adjust OpenClaw's behavior to work within current permissions.

Cause 6: Error Loop

OpenClaw may have entered a silent error state:

# Check for repeated errors
openclaw logs --level error --last 20

# Common error patterns:
# "Failed to parse message format" — platform API change
# "Model returned empty response" — model issue
# "Skill execution failed" — broken skill in chain

# Reset the error state
openclaw integration reset discord --channel general

Cause 7: Maintenance Mode

OpenClaw might be in maintenance or quiet mode:

# Check if quiet mode is active
openclaw config get group_chat.quiet_mode

# Disable quiet mode
openclaw config set group_chat.quiet_mode false

# Check scheduled quiet hours
openclaw config get group_chat.quiet_hours

Diagnostic Checklist

Prevention

• Set up health monitoring with alerts for disconnections
• Use channel-specific configs for busy vs. quiet channels
• Enable auto-reconnect with exponential backoff
• Review logs weekly for recurring warnings
