Unable to register Appium to selenium grid

I am trying to register Appium to local Selenium grid. Below are my steps:

  1. I am able to access grid console at


  1. I created below configuration json file:-


	"capabilities": [{
		"browserName": "Android",
		"version": "4.4.2",
		"maxInstances": 1,
		"platform": "Android",
		"deviceName": "4d0002174dca3161",
		"cleanUpCycle": 2000,
		"timeout": 30000,
		"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
		"host": "",
		"port": 4723,
		"url": "",
		"maxSession": 1,
		"register": true,
		"registerCycle": 5000,
		"hubPort": 4444,
		"hubHost": "",
		"hub": ""

The deviceName is from:

“adb devices” command

  1. When I started Appium with command

appium --nodeconfig C:\mobile\androidConfig.json

I am getting an exception

What am I doing wrong?


Ok, It was a silly typo.

“configurations” node was incorrectly written. It should be configuration “without an s”. In addition, on the platform side, it should be MAC or WINDOWS

node got successfully registered to the Grid after above changes.

Could it be possible to connect Android device to Grid connecting as a node with out node json file?

Hi all,

Error Coming while running multiple sessions using appium.Please let me know if any one knows about this.

I’m using different ports 4723, 4724 for two devices.,
