If your problem sounds like this, you're in the right place:

  • Connection Error: VALORANT has encountered a connection error. Please relaunch the client to reconnect. Error Code: VAN 140
  • What does VAN 140 mean?
  • I got kicked out of VALORANT and saw VAN 140.

Resolution

VAN 140 usually points to a startup or connection issue involving VALORANT, Riot Client, and Riot Vanguard.

Try these steps in order. We'll start with the quickest fixes first, then move into Vanguard-specific troubleshooting. Launch your game after each step to see if it worked.

  1. Update Windows. Windows updates can include security and system service changes Vanguard relies on. Install all available Windows updates and restart your PC.

  2. Update the Riot Client compatibility settings. This can help if Windows is applying launch behavior that gets between Riot Client, your game, and Vanguard.

    Show detailed steps
    1. Right-click the game shortcut on your desktop and select Properties.
    2. Go to the Compatibility tab.
    3. Check Disable fullscreen optimizations.
    4. Check Run this program as an administrator.
    5. Click Change high DPI settings.
    6. Check Override high DPI scaling behavior.
    7. Set scaling to Application.
    8. Click Apply, then OK.
    9. Repeat these steps for RiotClientServices.exe.
  3. Set the Vanguard service to start automatically. Having Vanguard installed won't do much good if it's not running when you try to play. If you don't use Vanguard Pre-Check to enable Vanguard to run on-demand, you'll need to set the Vanguard (vgc) service to Automatic.
  4. Remove and reinstall Vanguard. The quickest way to restore Vanguard's default settings is to manually uninstall it, then restart your PC and launch your game again to reinstall Vanguard.
  5. Reinstall your game. This can replace corrupted or missing game files that may be preventing Vanguard or your game from launching correctly. Follow our guide to uninstall and reinstall your game.
