Since this morning I get the above error when I log on to the Zyxel USG Flex 200 via the web interface.
And the web display is empty, nothing can be displayed or operated.
What can I do to resolve this error?

    Since today we are not able to login to our USG FLEX 700 (5.39 ABWD.1) via Web Interface. The USG login window is presented but when trying to login the browser retuns a 504 Gateway Timeout.

    Further any SSL VPN Logins via SecuExtender fail as well. Only VPN via IPSec is still available.

    Other services are still operable. For example we could reach the internet, and accesses from outside via port forwarding are working as well.

    Even in the SecuReporter, nothing is recorded, very strange. 🤔

    We have a similar issue since today. Our Atp200 didn´t work in the morning. I turned it off and after a reboot everything is working (Internet, VPN). But I can´t login to the atp "504 Gateway timeout". Whe hafe 2fa activated.

    Device "ATP200" is not connected. Please make sure device connection is stable so the log it uploads keeps SecuReporter running.

    Same problem with the device atp 200.

    There was an error when logging into the web interface: Wrong CLI command, device timeout or device logout.

    It doesn't allow access to the web interface right now. And the devices started to fall off. The Internet stops working

    When I log in to SecuReporter, I get this message:

    There seems to be a major problem with the services at Zyxel. 🙃
