OpenClaw Common Errors and Solutions: 15+ Issues Covered

Hey fellow developers!

I've been using OpenClaw for a while now and encountered my fair share of errors. Instead of solving each problem from scratch, I compiled a comprehensive troubleshooting guide covering 15+ common issues from installation to production.

  3. Runtime Errors (5 Issues)

1. Installation Errors

1.1 Installer Download Fails

Symptoms: curl: (60) SSL certificate problem or timeout.

Solutions:

Use Chinese mirrors:

npm config set registry https://registry.npmmirror.com/
curl -k https://openclaw.ai/install.sh | bash
Enter fullscreen mode Exit fullscreen mode

Windows manual:

iwr -useb https://openclaw.ai/install.ps1 -OutFile install.ps1
.\install.ps1
Enter fullscreen mode Exit fullscreen mode

1.2 Node.js Version Incompatibility

Error: Node.js version 18.x is not supported. Please use Node.js 24.x

Fix:

# nvm
nvm install 24
nvm use 24

# Windows: use nvm-windows
Enter fullscreen mode Exit fullscreen mode

1.3 PowerShell Execution Policy (Windows)

Error: File cannot be loaded because running scripts is disabled

Fix:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
Enter fullscreen mode Exit fullscreen mode

1.4 WSL2 Installation Issues

Enable features (Admin PowerShell):

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
wsl --update
wsl --set-default-version 2
Enter fullscreen mode Exit fullscreen mode

1.5 Installer Hangs

Diagnosis:

openclaw logs --follow
Enter fullscreen mode Exit fullscreen mode

Common causes: Invalid API key, proxy issues, firewall.

Fix: Retry or check network settings.

2. Configuration Errors

2.1 Invalid API Key

Error: Error: Invalid API key

Checklist:

  • OpenAI key starts with sk-
  • No extra spaces
  • Test: curl https://api.openai.com/v1/models -H "Authorization: Bearer YOUR_KEY"

2.2 JSON Syntax Error

Error: Error: Invalid JSON in config file at line XX

Fix:

openclaw config validate  # validates
openclaw config reset     # reset if needed
Enter fullscreen mode Exit fullscreen mode

Or use https://jsonlint.com/

2.3 Ollama Connection Fails

Error: Cannot connect to Ollama at http://localhost:11434

Fix:

# Check if Ollama is running
ps aux | grep ollama

# Start it
ollama serve &

# Test
curl http://localhost:11434/api/tags
Enter fullscreen mode Exit fullscreen mode

WSL2 note: If Ollama is on Windows host, WSL2 can't access localhost. Install Ollama inside WSL2 instead.

3. Runtime Errors

3.1 Port 8080 Already in Use

Error: Error: listen EADDRINUSE: :::8080

Fix:

Find and kill process:

# Windows
netstat -ano | findstr :8080
taskkill /PID <PID> /F

# Linux/macOS
lsof -i :8080
kill -9 <PID>
Enter fullscreen mode Exit fullscreen mode

Or change OpenClaw port:

openclaw config edit  # change "gateway.port" to 8081
openclaw restart
Enter fullscreen mode Exit fullscreen mode

3.2 Messages Not Arriving

Checklist:

✅ openclaw status

✅ Bot online (@botfather etc.)

✅ openclaw config validate

✅ Firewall allows port

✅ openclaw logs --follow

3.3 Feishu Webhook Verification Fails

Causes:

  • Domain not ICP-filed (required in China)
  • Invalid/expired HTTPS certificate
  • Nginx misconfiguration

Fix:

  1. Ensure domain is ICP-filed
  2. Use valid SSL (Let's Encrypt)
  3. Check Nginx config: 
   location / {
       proxy_pass http://127.0.0.1:8080;
       proxy_http_version 1.1;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "upgrade";
       proxy_set_header Host $host;
   }
Enter fullscreen mode Exit fullscreen mode
  1. Get correct URL: openclaw urls

3.4 Telegram Bot Privacy Mode

Issue: Bot doesn't receive group messages.

Fix:

  1. @botfather → /mybots
  2. Select bot → Bot Settings → Group Privacy
  3. Turn off
  4. Re-invite bot to group

3.5 Gateway Fails to Start

Diagnosis:

openclaw logs --level error --tail 50
openclaw config validate
netstat -ano | findstr :8080
Enter fullscreen mode Exit fullscreen mode

Common fixes:

  • Port in use → change port (see 3.1)
  • Config error → reset config
  • Permission denied → run as admin

4. Platform-Specific Issues

4.1 Feishu: URL Format

Correct: https://your-domain.com/api/plugins/feishu/events

Get it from: openclaw urls

Must be HTTPS, no query params.

4.2 Discord: 401/403 Errors

Causes: Wrong token, Message Content Intent disabled, insufficient permissions.

Fix:

  1. Re-copy Bot Token from Developer Portal
  2. Enable Message Content Intent (required!)
  3. Ensure bot has Send Messages + Read Message History permissions

4.3 WhatsApp: QR Code Issues

Check:

openclaw status
curl http://localhost:8080/api/plugins/whatsapp/qr
Enter fullscreen mode Exit fullscreen mode

Cloud server: Open port 8080 or configure Nginx reverse proxy.

4.4 Multi-Platform Message Conflicts

Enable user mapping to distinguish users across platforms:

{
  "plugins": {
    "common": {
      "userMapping": true
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

5. Performance & Production

5.1 High Latency

Optimizations:

  • Use local Ollama (< 1s latency)
  • Enable caching (TTL 3600)
  • Choose faster models (gpt-4o-mini, claude-3-haiku)

5.2 High Memory Usage

Limit cache:

{
  "cache": {
    "enabled": true,
    "maxSize": 1000,
    "ttl": 3600
  }
}
Enter fullscreen mode Exit fullscreen mode

5.3 SSL Certificate Expired

Renew:

certbot renew
systemctl reload nginx
Enter fullscreen mode Exit fullscreen mode

Set up cron for auto-renewal.

5.4 Service Crashes

systemd auto-restart (/etc/systemd/system/openclaw.service):

[Unit]
Description=OpenClaw Gateway
After=network.target

[Service]
Type=simple
User=yourname
WorkingDirectory=/home/yourname/.openclaw
ExecStart=/usr/local/bin/openclaw gateway
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target
Enter fullscreen mode Exit fullscreen mode

6. Best Practices

Pre-Installation

  • ✅ Node.js >= 24
  • ✅ Port 8080 free
  • ✅ Network connectivity

Configuration

  • ✅ openclaw config validate after each change
  • ✅ Test locally before production
  • ✅ Version control ~/.openclaw/

Monitoring 

openclaw logs --level error --follow
# cron: */30 * * * * openclaw logs --level error --tail 10 > /var/log/openclaw/errors.log
Enter fullscreen mode Exit fullscreen mode

7. Getting Help

Official resources:

When asking for help, include:

openclaw --version
openclaw config validate
openclaw logs --level error --tail 50
OS info
Reproduction steps
Enter fullscreen mode Exit fullscreen mode

Conclusion

Most OpenClaw errors are environment-related (Node.js version, network, permissions) or config mistakes.

Key takeaways:

  1. Check Node.js 24+ before install
  2. Always openclaw config validate
  3. Feishu needs ICP domain + HTTPS
  4. Local Ollama avoids network issues
  5. Backup config with git
