The error public key match failed means that during a fetch device-certificate operation, the firewall read the TPM’s sealed public key blob and compared it to a regenerated value – they differ. : the TPM validates the hardware identity.

Use tpm.msc to verify TPM is ready and not in reduced functionality mode.

The Trusted Platform Module (TPM) is a specialized chip on the firewall's motherboard designed to secure hardware through integrated cryptographic keys. When a Palo Alto Networks firewall boots, the TPM validates the hardware identity. The firewall’s "device certificate" is tied specifically to the public key stored within this TPM chip.
