If the hardware was recently replaced via an RMA, the cloud database must be manually forced to update. Log into the . Navigate to Assets > Devices . Locate the serial number of the problematic firewall.

Many community members have reported that a simple commit force resolved the issue for them. After the commit, attempt to fetch the certificate again. The firewall local certificate state or crypto files

The firewall must be able to communicate with Palo Alto’s CSP servers ( certificate.paloaltonetworks.com and api.paloaltonetworks.com ) to retrieve the certificate. This requires reliable outbound internet access from the firewall's management plane, a process that is often hindered by network security policies. Common network-related issues include:

Old software versions struggle to communicate with updated cloud infrastructure APIs.

typically occurs when a Palo Alto Networks firewall cannot validate its hardware-bound Trusted Platform Module (TPM) against the certificate it is trying to retrieve from the Customer Support Portal (CSP) Core Causes TPM/CSP Mismatch Navigate to Assets > Devices

Generate a new telemetry or registration token to reset the cloud relationship.

An existing, broken, or expired device certificate gets stuck in the local cache, forcing a key mismatch during renewal.
