Problem running wireless apps in android studio

Question

I’m having the problem of not being able to use the ADB Wireless function to get Builder and debug without needing USB cable.

I used plugins normally and never had problem, but I do not know if it was because of the update to Android 8.1.

Follow the steps I take today:

$ ./adb kill-server
$ ./adb tcpip 5555
restarting in TCP mode port: 5555

$ ./adb connect 192.168.0.107:5555
failed to connect to '192.168.0.107:5555': Operation timed out

^{I run these steps inside the android Platform-tools folder on a Macbook Pro}

I have checked the development options and they are the same as before.
