Network-pingdevice doesn't update anymore

I’m using network-binding since years now to ping devices and use their online-status.
currently with openHABian 1.9 with openHAB 4.1.1

Thing:

UID: network:pingdevice:handyThomas
label: Netzwerk Handy Thomas
thingTypeUID: network:pingdevice
configuration:
  hostname: 192.168.78.yy
  macAddress: F4:02:xx:xx:xx:xx
  refreshInterval: 60000
  retry: 2
  timeout: 50000
channels:
  - id: online
    channelTypeUID: network:online
    label: Online
    description: Gibt an ob das Gerät aktuell online oder offline ist.
    configuration: {}
  - id: latency
    channelTypeUID: network:latency
    label: Pingzeit
    description: Gibt an wie lange ein Ping in Millisekunden an das Gerät dauert.
    configuration: {}
  - id: lastseen
    channelTypeUID: network:lastseen
    label: Zuletzt gesehen
    description: Gibt Zeit/Datum an wann das Gerät zuletzt gesehen wurde.
    configuration: {}

the online-Channel is linked to HandyThomas_Online. The status didn’t change for some days:

after restarting the Thing it changed immediately:

is there something I can do?
