Before modifying configurations via the command-line interface (CLI) or opening a support ticket, force the system database to overwrite active runtime parameters. Navigate to the top right of the Web GUI. Click . Select Commit Force if available, or execute via CLI using: configure commit force exit Use code with caution.

The full error usually appears in three locations:

The error message typically occurs when a Palo Alto Networks firewall or GlobalProtect client cannot validate a device certificate because the Trusted Platform Module (TPM) hardware key on the device no longer matches the record on the server. This is often triggered after hardware changes, RMA processes, or deep OS updates that reset TPM states. Understanding the TPM Public Key Mismatch

to check your firewall's disk usage or system logs for these errors?

Ensure SCEP profiles include TPM key storage flag. Select Commit Force if available, or execute via

If the device certificate payload is dropped or truncated by upstream firewalls or WAN paths, reducing the Maximum Transmission Unit (MTU) size on the management port will prevent packet fragmentation. Go to .

In PAN-OS 11.0+, you can disable strict matching:

Think of the TPM as a ultra-secure vault inside the firewall hardware. Inside this vault, a unique private key is generated and locked away. The firewall uses this key to generate a Certificate Signing Request (CSR) to prove its identity to Palo Alto’s backend servers.

Before attempting complex resets, try forcing the firewall to refresh its local configuration state. Log in to the firewall CLI. Enter configuration mode: configure . Run a forced commit: commit force . Understanding the TPM Public Key Mismatch to check
