USG FLEX 50H / Intermittent Push Notification Issue

Suti

Hello

In a network environment with the following Zyxel products:

Firewall USG Flex 50h (dhcp), Switch GS1350-hp12 and Accesspoint NWA220AX-6E (Poe and power supply, both tested same problem, currently Poe) everything works fine after restarting the firewall.

After about 90-120 minutes, the Arlo cameras that access the Internet via the access point can no longer send push notifications. With the exception of one camera that is positioned directly next to the access point.

What could be the reason for this? After restarting the USG, it works again for a while. However, the video stream from the camera can be called up at any time. Only the push notification is no longer sent.

The cameras all have fixed IP addresses. I have already switched all security services (e.g. content filter etc.) off and on again, with the same result.

In the previous setting with alternative products, the cameras also worked without any problems.

I have replaced the Swisscom products with the hardware mentioned above.

In the log files, I see no evidence of packets being blocked.

Any ideas?

Hi @Suti,

Could you help collect diagnostic info on the firewall, switch, and AP so we can check this issue? Please help to collect when the firewall boots up and after this issue happens. We will verify the difference first to see what could be the problem.
