Does anyone experience issues with security heartbeat missing reported on XG firewall? One of our XG firewalls is continuously reporting couple of devices with missing heartbeat, which have been present on that network days/weeks ago (and are reporting healthy on daily basis), but still listed as missing in the firewall dashboard and generating event logs and alerts send to Sophos Central on daily basis. I have several hundred alerts per day in Sophos Central reporting missing Heartbeat from this firewall and the obvious suspects are two cashed endpoints, which are not even present on the network. We are currently on MR6 but this issue was present on previous firmware as well. I did report it with Sophos support but so far no luck..
