We have upgraded the PAN OS to the latest version 10.1.2 on 3 of 5 PA firewalls, including the LSVPN portal, and 2 of the satellite firewalls.
The thing is that 2 of the satellite firewalls with the latest PANOS 10.1.2 are unable to log in with the portal.

The rest of the satellites firewall with the PAN OS(10.0.x) are works as usual. No changes were made on the LSVPN configuration, both of the portal and the satellite.
