for adjusting the MTU or checking the current certificate status? TPM public key match failed - LIVEcommunity - 1239222
If you suspect the disk is full due to the accumulation of .pub_pem files, a TAC engineer can safely clean the directory. An alternative workaround for this bug is to reboot the NGFW, as this often clears out the temporary directory and allows the fetch to succeed.
To resolve this issue, work your way through the following steps, ranging from quick administrative fixes to advanced Technical Assistance Center (TAC) intervention. 1. Execute a Forced Configuration Commit The cryptographic hash or claim key registered on
Or use the TPM Management Console ( tpm.msc ) to check for "Matching" vs "Mismatched" keys under .
The "Failed to fetch device certificate. TPM public key match failed" error on Palo Alto Networks firewalls indicates a mismatch between the hardware Trusted Platform Module (TPM) and the certificate data registered in the Customer Support Portal. Troubleshooting involves re-generating the OTP, reducing the management interface MTU to 1374, or engaging Technical Assistance Center (TAC) for manual file system remediation.

Ensure that the TPM is properly configured and enabled on the device.
If you encounter this error, follow these troubleshooting steps sequentially, starting with basic administrative refreshes and moving toward cloud registration fixes. Step 1: Force a Configuration Synchronization
The "Failed to Fetch Device Certificate - TPM Public Key Match Failed" error is a specific issue that occurs on Palo Alto devices, typically when trying to fetch a device certificate. The error message indicates that the device is unable to retrieve the certificate due to a mismatch between the TPM (Trusted Platform Module) public key and the expected value.
Verify that your security rules allow traffic for the paloalto-shared-services app from the management interface. 2. Manual Certificate Fetch with OTP
