Teamviewer shows a computer is online, but it is in standby

almarc11

When I bring up my Teamviewer app, it shows under Managed Devices that one of my computers on my LAN is online. However, the same computer shows it to be offline under My Computers. If I try to wake it under My Computers I get an error saying it can't wake this computer. I have 3 computers on my LAN and the other two seem to behave. As far as I can tell, all the settings for each computer are the same. As you can see from

the attached screen shot, the HamPC shows it online under Managed Devices but offline under My Computers. Any help? Thanks in advance.
