If you’re trying to launch League of Legends and you’re hit with the dreaded Vanguard Error VAN 57, you’re not alone. This issue is becoming increasingly common, especially after Riot Games integrated the Vanguard anti-cheat system into League of Legends. In this guide, we’ll break down what this error means and walk you through the most effective solution to fix VAN 57 permanently.

❓ What Is Vanguard Error VAN 57 in League of Legends?

VAN 57 is an error code related to Riot Games’ Vanguard anti-cheat service. Originally designed for Valorant, Vanguard is now used in League of Legends to protect against cheats and exploits. The VAN 57 error usually occurs when Vanguard fails to start correctly, is disabled, or is blocked by system settings.

When this happens, you might see a message like:

“Vanguard Anti-Cheat has not initialized. Error VAN 57“

This prevents the game from launching and leaves players confused about how to get back into the game.

🛠️ Why Does VAN 57 Happen?

Here are the most common reasons why you’re seeing VAN 57:

  • Vanguard’s VGC service is not running

  • Background League of Legends or Riot processes are interfering

Luckily, fixing VAN 57 is straightforward if you follow the right steps.
