USG Flex no Nebula connection and gateway timeout after few hours of running
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:
The gateway did not receive a timely response from the upstream server or application.
zyxel support access is enabled
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.0
@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?
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.0
Any ideas how to unlock the firmware before the long weekend?
Anyone from Zyxel available to help? I can't find any solution. Zyxel support access is enabled0
Hello @baba I just unlock the upgrade feature, you may upgrade to the latest version now, thank you.1
Had same problem on Flex500 and Zywall 310. On Zywall 310 i was able reboot it ower inteface error and button "reboot", but with Flex500 problem solved only with reboot device with AC power loss.

I have no Radius server set with 220.127.116.11. Zyxel support is enabled, should I open a new thread?
