Hi,

This error is usually caused by a BIOS issue. Please update the BIOS on the system to the most recent BIOS available from the OEM to make the trusted computing base current.

Let me know if you are still having errors.

Sincerely,

Sahira

Thanks, @Sahira_Intel,

Indeed it is a virtual machine, on my other VM (same instance, same bios version), it works.

what happens if the host machine didn't register on the intel platform?

can it cause this problem?

Yes, you will get this 404 not found error if you have not yet registered the platform with Intel(r) Registration Service.

Regards.

Scott

Did registration solve your problem? How did you register your VM on the intel platform. I have the same issue, and my machine is Azure VM.
