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

  • Vanguard Error: VAN -101. An unexpected error with Vanguard has occurred and the client will now close.
  • What does VAN -101 mean?
  • League of Legends closed and showed error VAN -101.

Resolution

VAN -101 usually means Riot Vanguard detected an unsupported system configuration - or in other words, a system that doesn't meet League of Legends' system requirements.

If your current setup does not meet those requirements, you’ll need to use a supported computer or operating system before launching the game again.

Still having issues?

If your computer meets the League of Legends system requirements and you still see VAN -101, submit a ticket to Player Support. Make sure you attach your logs so we can take a closer look and help get you back in the game.
