Hi,

since 3 days my USG Flex 200 has no nebula connection after a few hours of running and i cannot login through the web interface. When I try to login with "support" username I get the following error:
Gateway Timeout

The gateway did not receive a timely response from the upstream server or application.

zyxel support access is enabled

Thanks!

    Hi @baba

    We have released ZLD5.36 Patch 2 firmware. This update primarily focuses on addressing vulnerabilities and resolving issues related to VPN connections and network interruptions.

    Hi @Zyxel_Stanley

    @Zyxel_James locked my firmware to a weekly version, because of an other bug fixed for me.

    Is this fix merged into 5.36 patch 2? Can you (or @Zyxel_James) help me to unlock and update?

    Thanks!

    Currently, the firmware version is V5.35(ABUI.0)ITS-23WK06-r107740 which is a dedicated version, so you will see the upgrade feature is locked, the device won't able to upgrade to a newer version till I unlock the feature.However, this bugfix will merge to the next version, I will help you to unlock it when V5.36 is available.

    @baba I suggest opening a new one since it's not the same subject as this thread, thanks.
