Adb connection Error:An existing connection was forcibly closed by the remote host

Issues/Bugs

Hi everyone,

I’m trying to execute the test script on Android - real device and keep getting this error:
Adb connection Error:An existing connection was forcibly closed by the remote host

-> result: cannot make a connection to device

It works beautifully when I run by emulator but when I change to real device, the error is keeps displaying.

Environment: Eclipse Neon - Appium 1.4.16.1

I wonder how it happens - is it because of the Port ?

I have tried to: kill-server and start-server also

Thanks, I’m appreciated for your help
