Hello everyone, like @BCC said this is an official status for the problem:

https://support.zyxel.eu/hc/en-us/articles/24159250192658-Firewall-Not-reachable-or-unresponsible-or-unable-to-boot-up

At the moment there is NO remote solution, only on premise.

Hi everyone,

We are regret this issue happens and any inconvenance we caused.

This issue is due to the Application Patrol signature issue.

Please reference this FAQ to resolve this issue:

Recovery Steps for USG FLEX/ATP Series Application Patrol Signature Issue (Jan. 2025) — Zyxel Community

BCC

@Zyxel_CSO thank you for the update article.
Since the FTP is actually functional on affected devices (see the image), can't we just upload the new firmware onto the affected device? If yes, what folder should that be?

FTP firmware upload would be a lifesaver as we can't imagine doing this physically on devices located far away from us.

When Automatik daily firmware update is activated, will it get the new Firmware or is the console sulution still needed.

Zyxel_Tobias

The issue can´t be fixed by FTP.

Automatic Daily firmware will NOT fix the issue if you are affected, then console firmware is required. If you are NOT affected, no action needed.

If it can no longer be repaired automatically, my USG Flex 200 is now a piece of electronic scrap, great! 😠
