what is the node config you're using?
here is an example
java -jar selenium-server-standalone-2.32.0.jar -role node -hub http://xxx.xxx.xxx.xxx:4444/grid/register -browser browserName=firefox
Replace the xxx with the actual ip address
Actually my HUB & NODE are in localhost. I have executed the below commands
HUB command
java -jar selenium-server-standalone-2.53.1.jar -role hub
Node Command
java -Dwebdriver.chrome.driver=C:\Users\shettarp\Music\chromedriver_win32\chromedriver.exe -Dwebdriver.ie.driver=C:\Users\shettarp\Music\IEDriverServer_x64_2.52.2\IEDriverServer.exe -jar selenium-server-standalone-2.53.1.jar -role webdriver -hub http://localhost:4444/grid/register -port 5557 -browser browserName=firefox,maxInstances=1 -browser browserName=chrome,maxInstances=1 -browser browserName=iexplorer,maxInstances=1 -maxSession 2
Wanted to know if we are working on local host, can i mention as localhost in NODE command or do i need to mention IP address.
The problem got resolved when i run the test case from office network in home network i am facing the issue.
