I have the same problem by using vb.net 2015. On BSP2.0 the problem was not there. Now I updated to BSP2.1b4 and when i click deploy, Visual Studio says after 20sec. this: “A connection attempt failed because the remote station did not respond properly after a certain amount of time, or the connection made failed because the connected host did not respond.” (I translated from German, sorry). But when I ignore the message everything works fine. But it sucks.
