If Valorant gives a VAN 9003 error, then this means that the system is asking you to enable TPM 2.0. This is a processor standard, it is either supported or not. Older models have TPM 1.0, 1.1, or other older versions installed. Using this technology, data is encrypted in the game before being sent to the server, so it must be enabled on the computer. If your PC supports TPM 2.0, you need to enable it. The easiest way to find out about support is to look at the technical specifications of the processor.
How to fix VAN error 9003 in Valorant?
A significant proportion of users who have encountered a similar problem were able to fix it by changing a few settings in the BIOS. The crash is especially common on ASUS computers, apparently due to some features of the pre-installed BIOS (UEFI).
- We restart the computer and at the moment when the prompt appears at the bottom of the screen, press F2, Del or another key (should be indicated in the line below). We need to get into the BIOS.
- We go to the “Advanced” section and select the “PCH-FW Configuration” tab.
- Click on the line “TPM Device Selection” and set the value to “Enable Firmware TPM”
- On the “Boot” tab, open “Secure Boot” – “Secure Boot Mode” and select “Standart”.
- For the “OS Type” parameter, set the “Windows UEFI Mode” option.
- We restart the computer through the “Exit” tab and check if Valorant is working.
Unfortunately, not everyone confirmed that this procedure worked for them. This may indicate either a compatibility issue or the absence of TPM 2.0. There may be some other reason for the error, but so far it has not been possible to find out. The instructions above are your best chance at fixing the VAN error 9003 that currently exists.
