A commit force is a low-impact, high-reward step. It reapplies the entire configuration, which can resolve transient inconsistencies and sometimes clears the failed certificate state.
A global bug has been noted where certificates on the device do not match those in the Customer Support Portal, often affecting newer models like the PA-440 during Zero Touch Provisioning (ZTP). Corrupt Certificate Store:

If the management interface relies on standard , packet drops can break the handshake process. Lowering the MTU prevents packet fragmentation.
If the firewall was recently deployed as an RMA replacement, the backend activation servers may still associate the certificate with the defective chassis. In this scenario, do not attempt further CLI modifications. Collect the output of show system info and show tech-support , then open a case with Palo Alto Networks Support to reset the TPM public key registration on the backend servers.
