[error]: Intel PCS server returns error(404).

[mmzz]

The BIOS version is the latest.
Tried initializing SGX by disabling SGX, booting the system, enabling SGX, and booting the system again.
It always prompts that registration cannot be completed.

Hello.

The platform manifest (which one of the warnings/errors speaks to) is not available.  This is the single requirement for registration.  Please try an "SGX Factory Reset" in the BIOS.  This will generate new platform keys and, therefore, a new platform manifest.  This should allow you to register.

You can read more about registration in our TDX Enabling Guide (SGX is currently a requirement for TDX attestation):  Infrastructure Setup - Intel® TDX Enabling Guide

Regards.
