Hello,

While I have not run into that situation, I would suggest going back to the 10.1 version you had before. The alternative would be to call support.

Regards,

Did you attempt to do that in one jump? Similar to running upgrades, I would never recommend skipping a major code version when running a downgrade. If you did, the benefit is that you can likely use SWM to revert to your last install.

1) Run 'debug swm status' to verify the partition PAN-OS version and ensure that it's showing revertible.

2) Run 'debug swm revert revert' to revert the active partition to your old partition.
