TPM Attestation Failed. Error: 0x80280009

We are getting an error during autopilot preparation. I am sure folks have seen this error - Securing your hardware (0x80280009). We're using Windows 11 Enterprise with the most updated BIOS and TMP version 2,49 on the HP site. The model is HP EliteOne 800 G4. Any thoughts?

@Esteban Cazarez Intune Thanks for posting in our Q&A.

Based on my search, I find someone met this similar issue with a ThinkPad P52 and that’s what worked for him.

Try to get info about TPM on the device. Open a cmd and enter this command: tpmtool getdeviceinformation. The output will show if the TPM firmware is vulnerable or no. If the firmware is vulnerable, try to update it. After that, reinstall the laptop and try again to see if it’s working. Please have a try and check if it works.

Hope it will help.
