Just for your information; all PC were showed as Offline, but, when I tried to login a targeted PC, it prompted the password and actually I could login it. Then the attempted PC remains Online. Once I closed the Viewer UI and reopened, all PC were showed as Offline again. Thank you.
Yes, that is the sequence here as well. Traffic shaping shenanigans at the datacenter?
FYI only, we recently installed "LAC Falcon" into most of PCs and servers as our Japan HQ requests. I'm not sure whether this is related to the issue that we can't view the RU Hosts. (But it was almost no problem last week.) LAC Falcon: https://www.lac.co.jp/english/service/operation/lacfalcon.html Thank you.
I'm not sure LAC Falcon have anything to do with that. This is more like issues on our side (or rather on the datacenter side). Currently the servers are up and running and being monitored. But if you have any issues just let us know.
