Hi Guys,

I am trying to run agent.jar command in my windows system to setup as a node in Jenkins. But it throws me the below error.

Hi@akhtar,

This type of error may occur because of network connectivity. Check your host IP address in Jenkins configuration. Also make sure your DNS server is updated according to your settings.
