Cannot reach node on virtual machine using Selenium Grid

selenium grid virtual-machine virtualbox nodes

I found a solution. VM (VirtualBox in my case) should be configured the following way:

Go to Settings -> Network
1. Attached to should be 'Bridged Adapter'
2. Expand 'Advanced' -> Promiscuous mode should be 'Allow All'

You are starting your RemoteWebDriver with wrong URL, you should give it hub IP to register on, not node IP.

WebDriver driver = new RemoteWebDriver(new URL("http://172.xx.xxx.248:4444/wd/hub"), capabilities);

This should solve your issue.
