Client disappears

The client may suddenly disappear after you log in. Usually, this is due to an authentication error or other miscommunication with your computer. To fix it, follow these steps:

Run the game as an administrator

  • Right-click on your League of Legends shortcut
  • Select Properties
  • Check the box labeled “Run as Administrator” under the Compatibility tab
  • Note: If you’re using Windows XP, you’ll need to log in as an Administrator instead

Sync your Windows clock

  • Right-click on your computer's clock and choose "Adjust date/time"
  • Select the Internet Time tab and click the "Change settings" button
  • At this point you may receive a UAC prompt. After this prompt, click the "Update now" button to resync

Temporarily disable your firewall

If you’ve installed a third-party firewall, try disabling them before logging in. Windows comes with its own firewall, which you can disable by following these steps:

  • Click on Start
  • Click on Control Panel
  • Click on System and Security
  • Click on Windows Firewall
  • Click on “Turn Windows Firewall on or off” (you may be prompted to enter the Admin password at this step)
  • Under each network location, select the “Turn off Windows Firewall” option
