Troubleshooting

Client Connection

If the p0 client isn't connecting or sending data, try these steps.

Client Won't Start

  • Check system requirements — p0 requires Windows 10 or later
  • Run as administrator — right-click p0 and select "Run as administrator"
  • Check for updates — make sure you have the latest version from the Downloads page

Authentication Issues

If the client can't sign in:

  • Check your internet connection — the OAuth flow requires a browser and internet access
  • Try signing in on the web first — make sure your account works at the Apex Racing website
  • Clear stored credentials — delete the p0 configuration folder at %APPDATA%\p0\ and restart the client

Client Connected but No Data

If the system tray shows connected but no sessions appear:

  • Check game telemetry settings — see Connecting Your Game
  • Complete a full lap — data is sent when you cross the start/finish line
  • Check the dashboard — there may be a brief delay before sessions appear

Firewall Issues

p0 needs outbound HTTPS access to send data. If you're behind a corporate firewall or VPN:

  • Allow outbound connections on port 443
  • Whitelist the Apex Racing domain in your proxy settings
  • Check if your antivirus is blocking p0's network access

Still Not Working?

If none of the above helps, try running p0 from the command line with debug mode to see detailed logs:

p0 --headless --debug

This will print connection status and any errors to the terminal.
