Fix: OpenClaw Not Responding — No Output After Install

TL;DR: Something in the chain is broken — auth, gateway, or channel connection. Use the checklist below to find it.

The Error

This one's tricky because there's no error message. You see:

• Blank terminal after sending a message
• WhatsApp/Telegram messages go through but get no reply
• openclaw command runs but nothing happens
• The process starts but produces zero output

$ openclaw
>

...and then nothing. No response, no error, just silence.

Why This Happens

OpenClaw has several components that need to work together: authentication, the gateway daemon, and your channel connection (terminal, WhatsApp, Telegram, Discord). If any one of them is broken, you get silence instead of an error.

The most common causes, in order of frequency:

1. Auth not configured — No API key set, or the key is invalid
2. Gateway not running — The background service isn't started
3. Channel not connected — WhatsApp/Telegram/Discord not properly linked
4. Model not specified — Config doesn't specify which model to use
5. Network issue — Can't reach the API provider

(GitHub #5030)

How to Fix It

Run through this checklist in order. Stop at the first failure — that's your problem.

Check 1: Is the gateway running?

openclaw gateway status

Expected: Gateway is running (PID: xxxxx)

If not running:

openclaw gateway start

If it fails to start, check the logs:

openclaw gateway logs --tail 50

Check 2: Is authentication working?

openclaw health

Expected: Green checkmarks for your configured providers.

If auth fails: You need a valid API key. See our guides for:

• OAuth token blocked (most common)
• Auth config mismatch

Quick fix — set the key directly:

export ANTHROPIC_API_KEY="sk-ant-your-key-here"
openclaw gateway restart

Check 3: Is your channel connected?

openclaw status

Look for your channel (WhatsApp, Telegram, Discord) in the output. It should show connected.

If you're using the terminal and getting no output, try forcing a direct test:

openclaw chat "Hello, are you there?"

If using WhatsApp:

openclaw channel whatsapp status

If using Telegram:

openclaw channel telegram status

Check 4: Is a model configured?

cat ~/.config/openclaw/clawdbot.json | grep -i model

You should see something like:

"model": "claude-sonnet-4-20250514"

If missing, add it to your config:

{
  "model": "claude-sonnet-4-20250514"
}

Check 5: Can you reach the API?

curl -s https://api.anthropic.com/v1/messages \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "content-type: application/json" \
  -d '{"model":"claude-sonnet-4-20250514","max_tokens":50,"messages":[{"role":"user","content":"Hi"}]}' \
  | head -c 200

If you get a response, the API is fine — the problem is in OpenClaw's config.

If you get a timeout or connection error, check your network/firewall.

Check 6: Check the logs

When all else fails, the logs will tell you what's happening:

# Gateway logs
openclaw gateway logs --tail 100

# Or find them manually
find ~/.config/openclaw -name "*.log" -exec tail -20 {} \;

Look for lines containing error, failed, timeout, or rejected.

How to Prevent It

• Run openclaw health after any config change. Make it a habit.
• Set up all auth before connecting channels. Auth issues are the #1 cause of silent failures.
• Check logs first, ask questions second. The answer is almost always in the logs.
• Start simple. Get terminal chat working before connecting WhatsApp/Telegram/Discord.
