Previously it is working fine. I started Selenium grid node using python. From then onwards i am getting this problem.

Thanks in Advance.

Answer 1

What OS are you using? If you are using a *nix system can you do:

netstat -tulpn | grep :4723

if there is any result then just kill that process.

You can try running:

  Windows: taskkill /F /IM node.exe
  Linux: killall node
  Mac: killall node

Try also installing a new version of appium from npm.

Answer 2

It looks like server is already in running mode. If you want to start the again, please stop the running server first.

Other case can be that same port is used by some other process.

Answer 3

Maybe you have start appium server before when you want to start appium app; If this condition,shutdown the appium server, then restart appium app or client.

note: If you killall node, the appium server also be killed.
