How to fix the VAN 9005 error
The VAN 9005 error is caused by certain settings in your computer's BIOS, its core operating system, not being compatible with Vanguard. If you don't know what you're looking for, it can be hard to tell why Vanguard isn't happy with you.
This is one of Vanguard's more technical error codes, and requires more than a Task Manager. You're going to need to restart your PC to do this, so it's best to consult this article on your phone.
- Turn off your PC, then turn it back on
- As the PC is restarting, Hold F2
- This should prompt the computer to boot up the BIOS, from which you can change core characteristics about how your PC is behaving.
- Navigate to the Security tab
- Configure your TPM 2.0 setting as follows: TPM 2.0: Enabled
- Navigate to the boot manager tab
- Select Unified Extensible Firmware Interface (UEFI) as the boot mode, it was likely in Legacy previously.
- Save the settings and restart your PC.
That should solve the VAN 9005 error, as Vanguard requires a UEFI boot and TPM 2.0 to be enabled at the same time. These setting should stay in place from now on, so you shouldn't have the same problem logging into League of Legends unless you change the settings again.
Hopefully you're back to LoL in good time, for any non-Vanguard LoL errors, consult our complete client error guide.
