I get the same problem, on a local machine, 3 meters from me, with no firewall active, just after I've disconnected and tried to reconnect, on the same switch.
I also have problems connecting to a remote machine, but I get no error, it just continually says "connecting...".
Neither the machine near me nor the remote machine show any signs of an error, according to Teamviewer they are connected and all is good.
Incidentally I tried to remotely restart the remote computer and all services disappeared from the internet except Teamviewer. When I got to it's location it was telling me "Teamviewer minimised" was stopping Windows from shutting down, did I want to force close. VERY VERY Annoying.
