Android adb: No connection could be made because the target machine actively refused it [duplicate]

Question

Help needed.

PC-Windows 10, Samsung S4 without simcard(connected to same wifi with PC, connected to PC thru USB).

So far. I've already tried uncheck/check USBDebugging, unplug/plugin USB, on/off Wifi, just couldn't get connection...What can possibly be wrong?

C:\Users\junew>adb devices

List of devices attached

C:\Users\junew>adb connect 192.168.0.27

unable to connect to 192.168.0.27:5555: cannot connect to 192.168.0.27:5555: No connection could be made because the target machine actively refused it. (10061)(nothing pops up on my screen)

C:\Users\junew>adb kill-server

C:\Users\junew>adb usb

* daemon not running; starting now at tcp:5037

C:\Users\junew>adb connect 192.168.0.27

unable to connect to 192.168.0.27:5555: cannot connect to 192.168.0.27:5555: No connection could be made because the target machine actively refused it. (10061)(Window pops up on Samsung screen, but still unable to connect)

Answer 1

1.Connect PC and device with USB cable. 2.Input below commands:

  adb kill-server
  adb tcpip 5555
  adb connect YourDeviceIpAddress(e.g 192.168.0.27, you could ensure it via viewing device configuration)
