If your problem sounds like this:

  • VANGUARD ERROR: VAN 7003. An unexpected error with Vanguard has occurred and the client will now close.
  • I received a Vanguard error when trying to enter a League game.
  • What does VAN 7003 mean?

Resolution

VAN 7003 occurs when Vanguard cannot detect an active League Client UI during initialization. A known cause is having the Close client during game setting enabled in the League Client, which causes the client UI Vanguard expects to detect to close when entering a game.

To resolve this error, follow these steps:

  1. Open the League Client settings.
  2. Locate Close client during game and turn the option off.
