Check Last seen. A dash means the station has never connected, which is a setup problem, not an outage. A time such as "Offline 3 hr" means it was working and stopped.
Try remote access. If the remote desktop opens, the machine is up and only the station application is down. Use Restart app and the connection badge should recover within a minute.
If remote access connects and then drops immediately, the machine is powered off, asleep or off the network. Someone at the venue needs to check power and the network cable.
If it only just went offline, give it a minute. Disconnects are reported with a short delay.
