"WaitforConnectFailed" issue

Hi everyone,

Over the past few weeks, I haven't been able to connect to my other computers through Teamviewer. Everything was fine during the last few years.

All my computers appears online but when I try to get access to one of them, after the "Connecting..." message, I get an error message saying that "No connection to partner. / Partner didnt connect to router. / Error code: WaitforConnectFailed".

Strangely enough, the connection succeeds some times (1 every 100 or so), for no apparent reason. Two of my computers are on the same network but it does not make any difference.

I'd really appreciate any help on this...
