EK certificates TPM

[Voornaam]

Laptop: Asus N552VX
OS: Windows 11 Pro
CPU: Intel i7-6700HQ
BIOS: latest version

My laptop shows "Attestation: not supported"

I have tried: resetting the TPM, reinstalling Windows 11. But nothing works.

I suspect this issue is related to the following: When I run "tpmdiagnostics EKCertificateURL" in elevated PowerShell, I receive a RSA and ECC-URL.

• RSA:  https://proserv.intel.com/ekcertservice/REDACTED
• ECC: https://proserv.intel.com/ekcertservice/REDACTED

The RSA-URL works, but ECC-URL does not. This indicates a problem with the EK certificates availability.

Please find additional information below, and a screenshot of the attestation status problem, with the output of: "Intel system support utility", attached
