    Dear all,

    We have in use 2 USG Flex 500 in HA, after the upgrade 5.36, same issues as yours, randomly stucks.

    We have only IpSec/L2TP VPN users and also to after disabling the MFA the firewalls stukcs.

    I noted that also too, that the HA feature is not working, when one firewalls stucks and I reboot it, the other one in HA didn't go live and need to be rebooted too.

    Now I let one Firewall off, because I noted that after a while the backup one in HA anyway stucks.

    I hope in a prompt resultion, it is not accetable that such things happens to production enviroments…Last time it happens with Application Patrol Signature issue and I get out the mud only because the other firewall in HA didn't reboot, otherwise it would be a disaster.

    The lack of trust is now Huge.

    Please give us any Feedback to try to solve!

    @Zyxel_Cooldia are you in the condition to share what's missing for release?
    Soon is better than "not soon" but it's worse than "friday next week" for scheduling the upgrade/reboot procedure.

    We have 2 ATP 500 in HA in use, has anyone already installed the firmware 536ABFU0ITS-23WK17-r109100? Any feedback on random blocks? Should I wait for patch 1 to be released for system stability?

    I haven't installed that one, but it's dated April 28 and the changelog doesn't mention any fix for the issues in this thread. So I think you should wait for patch 1.

    Unfortunately, the lack of changelog for lab firmware is… leading to a coin flip for "go for" or "wait until".

    Dear @Zyxel_Cooldia,

    Dear all,

    I updated with this firmware

    V5.36(ABUJ.0)ITS-23WK17-0504-230401495D / 2023-05-04 10:35:09

    and in the past 48h the firewall seems work fine without strange behaviours.

    Today all "heavy users" will come back to work and I will updated in case of "misbehaviours".

    Same here,

    Firmware V5.36(ABWD.0)ITS-23WK17-0504-230401495D, which Zyxel gave me for testing, it's now running since 4 days and I didn't have any issue so far. It has been testing with more than 15 SSL VPN users connected

  • Hello,

    Is there any timetable when this gets released?
    We need that fix as I do not want to reboot my USG Flex 700 every 2-3 hours
