: A hardware-to-portal discrepancy where the device’s unique TPM signature does not match what Palo Alto’s backend expects, often due to an invalid existing certificate or a backend bug. MTU Size Constraints

If the error persists, try clearing the local telemetry cache and forcing a refresh: Run the following commands in the CLI:

: An existing, invalid, or expired device certificate remains in the system, blocking the generation of a new one even with a valid One-Time Password (OTP).

: During manufacturing, a unique cryptographic key pair is burned into the TPM chip.
