Teamviewer connection failed no route

I have a network of computers in my office that I control from my Teamviewer app. But when I try to connect to them, recently an issue started showing up. After updating to the recent version, sometimes it is showing an error “Teamviewer connection failed, no route.” What does it mean? Is there any fix for this issue? it gets really irritating when I urgently want to connect to the computers. And I can’t.
