For a long while now , the function to block devices in the Device insight list is not working . Or it may work 1 in 1000 tries. What can be done ? firmware on it v1.37 .

    Hi @Stefan_Sweden_2026

    May I know the behavior that block devices not working? Do you mean you can't block it or the device can still access the Internet? Please help to share more details with us, so we can clarify this issue.

    Hi , we are trying to use Device Insight to block non allowed devices . We want to create a block list of devices that will remain permanent and those devices should not be able to connect and get a dhcp ip . It was something that worked in the past. But then some y back started failing . As the USG we had was old. We upgraded to new a USG FLEX 50H , but it has not worked at all with the new one. When you check a device and choose add to block list . Then refresh , device appears still connected and block list empty.
