How to Fix Valorant VAN Error 9001 [2023]

Valorant VAN Error 9001 or 9003 only appears only for Windows 11 users on the devices where TPM 2.0 and Secure Boot feature is turned off. Riot has enforced the primary requirement of both Secure Boot and TPM 2.0 (which is also essential for Windows 11). So, follow our article to quickly turn ON both features and start enjoying the game.

NOTE – If you have bypassed the TPM 2.0 check while installing Windows 11 as your system doesn’t have one, there is no way you can play Valorant. You can’t fool Vanguard. You have to go back to Windows 10 to enjoy Valorant.

Fix 1 – Turn Secure Boot, TPM features ON

Usually, both Secure Boot and TPM 2.0 features are turned ON by default. But, if you are using an older system, you have to tweak the settings manually in BIOS.

Step 1 – Boot into BIOS mode

Step 1 – Open Settings from the Start menu.

Step 2 – If you go to the left pane, tap the first option “System“.

Step 3 – Now, if you scroll down you can find “Recovery” settings. Open that up.

Step 1 – Using the Windows key and the R keys together, open Run.

Step 2 – Then, type this in the blank box. Click “OK” to open the Local Group Policy directly.
