Troubleshooting
Running into issues? Here are solutions to common problems and frequently asked questions.
Common Issues
Connection Refused / Tunnel Won't Start
Problem: The agent can't connect to the Portex server.
Solution:
- Check your internet connection
- Verify that port 443 (HTTPS) and WebSocket connections aren't blocked by your firewall
- Try running with
--verboseflag for detailed logs
Local Server Not Responding
Problem: The tunnel is active but requests return 502 Bad Gateway.
Solution:
- Ensure your local server is actually running on the specified port
- Test locally:
curl http://localhost:3000 - Check if another process is using the port:
lsof -i :3000
Subdomain Already Taken
Problem: You get an error that your custom subdomain is unavailable.
Solution:
- Try a different subdomain name
- If you previously used this subdomain, log in to release it from your account
- Premium users can reserve subdomains permanently

Is Portex free?
Yes! Portex offers a generous free tier with unlimited tunnels and basic features. Premium plans add custom domains, extended logs, and priority support.
Do I need to create an account?
