VAN 21 typically appears when Valorant is launched without Riot Client handling the authentication handshake. Always open Valorant through Riot Client — launching the .exe directly bypasses the auth flow and triggers this error.
What does Valorant VAN 21 mean?
VAN 21 is an authorization check failure. Riot Client acts as the gate that passes your account credentials and Vanguard status to Valorant. When you bypass it, Valorant cannot confirm your identity or that Vanguard is properly running.
Other causes
Even when launched via Riot Client, VAN 21 can appear if Vanguard failed to start, if Riot Client's session token expired, or if your PC clock is significantly out of sync (authentication tokens are time-sensitive).
Regional restrictions
In some regions, VAN 21 appears due to account region mismatch — for example, playing on an account registered in a different region than your current server selection. Check your Riot account region in account settings.
How to fix step by step
- 1Close Valorant, close Riot Client completely (check system tray), then reopen Riot Client and launch Valorant from there.
- 2Restart your PC and let Vanguard load before opening Riot Client.
- 3Right-click the Vanguard tray icon and restart it if it shows an error state.
- 4Sync your Windows clock: Settings > Time & Language > Sync now.
- 5Log out of Riot Client, log back in, and relaunch Valorant.
- 6Reinstall Riot Client and Vanguard if the error persists after the above steps.
How VAN-21 differs from related codes
- Error VAN-1: Vanguard, Valorant's anti-cheat system, is not running or failed to initialize, so your client is not authorized to launch a match. (user-side)
- Error VAN-39: Vanguard's kernel driver is not loaded, is outdated, or requires a system restart to activate after an update. (user-side)
