title: Android adb: No connection could be made because the target machine actively refused it
body: <p>Help needed. </p>
  
  <p>PC-Windows 10, Samsung S4 without simcard(connected to same wifi with PC, connected to PC thru USB).</p>
  
  <p>So far. I've <strong>already tried</strong> uncheck/check USBDebugging, unplug/plugin USB, on/off Wifi, just couldn't get connection...What can possibly be wrong?</p>
