How to fix the VAN 9001 error in League of Legends

The VAN 9001 error is caused by not having TPM 2.0 enabled in Windows 11. TPM is a Windows 11-exclusive, hardware-based security function of your PC. It can be toggled on or off from your BIOS, and sometimes computers can boot with TPM 2.0 disabled. Here's how to access your BIOS and fix the VAN 9001 error.

Verify TPM 2.0 is supported

  • Open the Windows search function
  • Search for 'tpm.msc'
  • If TPM 2.0 is unsupported: You should get an error message that says "Compatible TPM cannot be found"
  • If TPM 2.0 is supported: Windows will open a window labelled Trusted Platform Module (TPM) Management On Local Computer. If this appears, make sure the information in the windows reads as follows:
    Status: The TPM is ready for use
    Specification Version: 2.0

How to enable TPM 2.0 in BIOS

How to navigate your computer's BIOS can be confusing, and it varies by manufacturer. It's always worth finding somebody familiar with PCs if you're feeling lost. Otherwise, you can consult your motherboard's manufacturer's instructions, many of which are available online.

That's all you need to know about the VAN 9001 error in League of Legends. Once TPM 2.0 is enabled and functioning properly, you should be able to get right back to League of Legends. If none of this works, you're best off contacting your motherboard's manufacturer or Riot Games support directly.
