Troubleshooting OpenClaw: Common Issues and How to Fix Them

Every tool has its quirks. OpenClaw is powerful, but when something breaks, the error messages aren't always self-explanatory. This guide covers the most common issues users hit and how to resolve them fast.

Installation Errors

Node.js Version Mismatch

OpenClaw requires Node.js 18+. If you see errors during installation:

# Check your Node version
node --version

# If below 18, upgrade
nvm install 20
nvm use 20

Using a Node version manager like nvm prevents conflicts with other projects requiring different versions.

Permission Denied During Install

On macOS or Linux, you might encounter permission errors:

# Fix: Don't use sudo, use a Node version manager instead
npm install -g openclaw

# If permission denied, fix npm's default directory
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Installation Completes but Command Not Found

After a successful install, running openclaw returns "command not found":

Check that npm's global bin directory is in your PATH:
```
echo $PATH | tr ':' '\n' | grep npm
```
If missing, add it:
```
export PATH="$(npm root -g)/bin:$PATH"
```
Verify installation:
```
openclaw --version
```

Connection Issues

Gateway Won't Start

The Gateway service is the backbone of OpenClaw's connectivity:

# Check if something is already using the default port
lsof -i :18789

# If port is in use, either kill the process or change the port in config
openclaw gateway stop
openclaw gateway start --port 18790

Agent Can't Reach External APIs

If agents are timing out when calling model providers:

Verify internet connectivity from the machine:
```
curl -I https://api.anthropic.com
```
Check proxy settings — corporate networks often require proxy configuration:
```
export HTTPS_PROXY=http://proxy.company.com:8080
```

Verify API key is valid by testing with curl:

curl https://api.anthropic.com/v1/messages \
  -H "x-api-key: YOUR_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -d '{"model":"claude-opus-4-5","max_tokens":10,"messages":[{"role":"user","content":"test"}]}'

Check firewall rules — ensure outbound HTTPS (port 443) is allowed.

Node Companion App Won't Pair

Pairing failures usually stem from network or configuration issues:

Same network required for initial pairing — the companion app and Gateway must be on the same local network.
Check Gateway URL in the app settings matches your server's actual address.
Restart both devices — sometimes a fresh start resolves discovery issues.
Check QR code validity — codes expire after 5 minutes. Refresh if expired.

Model Errors

"Model Not Found" or "Unsupported Model"

This error occurs when the model identifier doesn't match what the provider expects:

# Use exact model names from provider documentation
# ❌ Wrong
"model": "claude-v4"

# ✅ Correct
"model": "claude-opus-4-5"

Check the Anthropic model list, OpenAI models, or your provider's documentation for exact identifiers.

Rate Limit Exceeded

You're hitting API quota limits:

Check your current usage in the provider's dashboard.

Implement exponential backoff in your code:

async function callWithRetry(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (e) {
      if (e.status === 429) {
        await sleep(Math.pow(2, i) * 1000);
        continue;
      }
      throw e;
    }
  }
}

Consider upgrading your plan or distributing load across multiple API keys.

Context Window Exceeded

Your prompt plus conversation history exceeds the model's maximum context:

Start a new conversation when context grows too large.
Summarize and compress long-running contexts before continuing.
Choose models with larger context windows (Claude Opus 4 has 200K tokens).

Performance Problems

Slow Response Times

If agents feel sluggish:

Check network latency to your API provider:
```
ping api.anthropic.com
```
Reduce verbosity in agent instructions — less processing means faster responses.
Use streaming if your setup supports it — results stream incrementally rather than waiting for full response.
Switch to a closer region — many providers have multiple regions. Lower latency = faster responses.

High Memory Usage

OpenClaw shouldn't consume excessive RAM, but long-running sessions can accumulate:

Restart the Gateway periodically to clear memory.
Limit conversation history stored in context.
Check for memory leaks in custom plugins by monitoring over 24-48 hours.

Agent Gets Stuck in Loops

Agents occasionally repeat actions without progressing:

Set explicit iteration limits in your configuration:

{
  "execution": {
    "max_iterations": 20,
    "max_tool_calls": 50
  }
}

Be more specific in your instructions — vague goals cause looping.
Break complex tasks into smaller steps with intermediate verification.

Debug Tips

Enable Verbose Logging

When something goes wrong, turn up the detail level:

openclaw gateway start --log-level debug

Debug logging shows every API call, tool invocation, and state change. Reproduce your issue with this enabled and you'll have a clear trail.

Use the OpenClaw CLI for Diagnostics

# Check system status
openclaw status

# View recent logs
openclaw logs --lines 100

# Test configuration
openclaw config validate

Isolate the Problem

When debugging complex setups:

Simplify your configuration to minimum viable settings.
Test in isolation — run one agent with one model.
Add components back one at a time until the problem reappears.
Document what changed — often the last thing you changed is the culprit.

Check Provider Status Pages

Before assuming it's your setup, verify the provider is healthy:

Outages happen and knowing this upfront saves hours of debugging.

Getting More Help

If you've worked through this guide and still can't resolve the issue:

Search existing issues at the OpenClaw GitHub repository.
Check the documentation for updates on known issues.
Ask in Claw Crew — the community often has workarounds for edge cases.
Collect diagnostic info before reporting:
```
openclaw diagnostics > output.txt
```

Include your OS, Node version, OpenClaw version, and exact error messages when seeking help.
