This error happens when the IDE failed to connect to the device. It can happen because the app crashed at startup or because of a firewall or some other network problem.
Thanks Erel for your tip. I still don't understand why there shouldn't be a connection so often. Try the Windows Firewall
turn off temporarily.
I'll post logs correctly soon.
You should always restart the USB connection if the phone gets disconnected from USB cable (or loose cable), the ADB (Android Debug Bridge) gets dizzy.
