Hi Guys,

I am trying to set one Cloud Node in Jenkins. But it gives me the below error.

java.net.ConnectException: Connection refused

Hi@akhtar,

You may get this error if you didn't allow your jenkins node to connect with Docker server. Open your docker configuration file and make changes as shown below.

$ vi /usr.lib.systemd/system/docker.service

Add your host server IP with port number and restart docker service.

$ systemctl daemon-reload
$ systemctl restart docker
