Connection Issues

Troubleshoot problems connecting to the C3 server.

Common Issues

Can't connect to server

  • Verify the server is running (check terminal output)
  • Ensure correct host and port in app settings
  • Check if firewall is blocking the connection
  • Try disabling VPN on both devices

Connection drops frequently

  • Check WiFi signal strength
  • Ensure server machine isn't going to sleep
  • Try reconnecting from the app settings

Local Network

Both devices must be on same network

Verify both your phone and computer are connected to the same WiFi network. Guest networks often isolate devices.

Find your local IP

# macOS / Linux
ifconfig | grep "inet "

# Windows
ipconfig

Firewall issues

On macOS, you may need to allow incoming connections. On Windows, check Windows Defender Firewall settings.

Remote / ngrok

ngrok tunnel not working

  • Verify your ngrok token is correct
  • Check ngrok dashboard for tunnel status
  • Ensure authentication is configured

Authentication failed

  • Double-check username and password
  • Ensure SSL is enabled in app settings
  • Try regenerating credentials and reconnecting

Check Server Output

The C3 server logs connection attempts. Check the terminal for error messages that can help diagnose the issue.
