What to do?

 

Have you allowed Unity to access the network through Windows Firewall? This seems like an issue that could be caused by that, perhaps try adding an exception to Windows Firewall for Unity then trying again. Mircrosoft have a good tutorial for adding exceptions to the firewall here; http://windows.microsoft.com/en-gb/windows/communicate-through-windows-firewall#1TC=windows-7

 

Yeah I allowed it private. And now I allowed it private and public, but didn't working..
My question is: I need to allow it only public? To work?

 

Hmm, I allow it only Public, and didn't working again..

 

Try disabling direct X 11 - http://docs.unity3d.com/Manual/DirectX11.html

 

How to disable it?

 

http://docs.unity3d.com/Manual/DirectX11.html

"To enable DirectX 11 for your game builds and the editor, set “Use DX11” option in Player Settings. Unity editor needs to be restarted for this to take effect."

So the opposite.

 

Thank you so much!!!!!!
