We did it about 5 times and got everytime a "now" in agent last online. But after 45 min SM showed the status as shown in the image. The only way I could assume the device as offline is, because the actions sent to the device where hold on pending.
Yes, but I need to know what time is used where SM says, "OK I give up this device is offline"
If I'm forcing a device 5 times to check in and there is no response, but SM says it's online "now" there must be a trigger of time when SM "switches" the device as offline. In this case it took 45 min and this is a very long period.
