adb connection over tcp not working now

Question

I was trying to use adb over TCP/IP. I have followed these steps

adb tcpip 5555

adb connect 194.68.0.100:5555

I have used my device for 2 days and now I am unable to connect to my IP address like when I do

adb tcpip 5555

it doesn't respond anything. Anyone knows what could be the scenario.

Answer 1

Thanks to sud007 for this answer. In my case, I only need this part of the solution:

In CMD/Terminal:

$ adb kill-server

$ adb tcpip 5555
restarting in TCP mode port: 5555

$ adb connect 192.168.XXX.XXX

This bug brings more errors than unable to connect to 192.168.XXX.XXX:5555: Connection refused. In my case, I could connect to the device, but when you try to run the app. AndroidStudio stay in Installing APK forever. In this case, I needed to restart the phone too.
