Active-Passive firewall globalprotect clientless error code -1

[SShnap]

Hi, something strange start showing, I am using more than two years active-passive firewall with global protect client and clientless portals.

suddenly now when I move the traffic to the 2nd firewall the clients are receiving this error code -1.

on the 2nd firewall under monitor-log-global protect,  I notice some logs of "Success - quarantine - quarantine delete" but we are no using active HIPS only monitor and alert.

Once I move back to the 1st firewall everything works fine no error.

firewall is in version 10.0.8H4

global protect 5.2.6

thank you all

Hi, I was able to identify the problem, there was a time gap between the two units of 5min, so it caused the authentication error and the global protect data file to not being updated.

hope it will save some others time for finding what the error code -1 means
