问题
I cannot use adb connect to connect via wifi to my device (nexus 5, android 6), but since i'm developping a cordova plugin using usb OTG, I really need to connect via wifi.
I tried to adb kill-server, and all solutions provided on SO, and noone is working for me...
Before it was working ok (i.e android 5).
Any idea?

I had the same issue since the android 6 upgrading. I noticed that for some reason the device is playing "hard to get" when you try to contact it over WIFI.
Try these following steps:
Make sure that
Aggressive Wi-Fi to Cellular handoverunder Networking section in the device's developer options is turned off.ping continuously from your pc to the device to make sure it's not in network idle mode
ping -t 192.168.1.10(windows cmd), unlock the device and even try to surf to some website just to make it get out of the network idle.If ping doesn't work, turn off / on Android Wifi and go back to step 2.
When it replies to the ping, connect it via usb, and:
adb usb
adb tcpip 5555
adb connect 192.168.10.1:5555
In case it's still not connected, try to switch the usb connection mode as MTP / PTP / Camera while the device is connected through usb and repeat these steps over again...
If the above points are not working please try running adb as admin. For Ubuntu -
sudo adb start-server

In my case I had to shut of and on the wifi adb debugger app, on the device. On another USB device I had to shitch off and on developer mode, then re-set the development options. Also reset my pc.
Seem that adb in some way made a mess with global communication and all the debug communication have to be reset on both sides.
After this the devices start to comunicate again

The critical step in getting this to work is disconnecting the usb cable after issuing the adb connect xx.x.x.xx:5555 command. At this point you are connected but unauthorized. Execute adb kill-server and re-issue the connect command. Verify with execution of adb shell date.

sudo adb start-server
Just worked for me. after A day of looking for a solution.
