I use ip range scanning for devices and things were working ok up until some time ago. Now I have 77 devices that are not getting scanned (either that or it is not updating the last seen date).
I can ping the devices that are no longer showing up (from the server). I can run the device tester (from the server) and that works fine on each device.
The report I'm using is a canned report: Device: Not seen in the last 30 days
Can you help?
