Editor attaching stops working

Hi community,

I am using Unity 5.2.1f1 with Visual Studio 2015.
I was very happy, when I saw, that Unity can work together with Visual Studio so I set it all up and it works fine. Until a certain point, that is apparently by random, when Unity stops working together with VS. VS thinks everything’s fine but Unity doesn’t react.
Editor Attaching is turned on and Visual Studio 2015 is selected.

I really searched by heart on the internet but either no one has the same problem or I can’t describe it properly in the search boxes.

I hope someone can help me.

Regards

Try upgrading to Unity 5.2.2 as they seem to have made several improvements regarding debugging.
