: Some users report that a simple "Commit Force" from the GUI or CLI can clear transient state mismatches. Known Issues & Technical Causes The TPM is a microcontroller that stores RSA

To understand the gravity of a "public key match failure," one must first understand the role of the TPM. The TPM is a microcontroller that stores RSA cryptographic keys specific to the host hardware. In a Palo Alto firewall, the TPM is utilized to anchor the device’s identity. When the device is booted or when it attempts to establish a secure channel (such as SSL decryption or management plane communication), it relies on a device certificate. : Lower the Management Interface MTU to 1374

: Lower the Management Interface MTU to 1374 if you suspect packet fragmentation is causing the fetch to time out.
