Splunk uninstallation / kill command failed -- Connection Refused error on port 22

Hi, I was trying to uninstall Splunk due to some issues in existing installation. I followed the steps for "Uninstall Splunk Enterprise manually" as mentioned on below link: https://docs.splunk.com/Documentation/Splunk/7.0.0/Installation/UninstallSplunk But as soon as I executed the below command (as directed on above link), the next moment, I got Connection Refused error port 22 for the server. I don't know how is this related, any hint will be really helpful. kill -9 `ps -ef | grep splunk | grep -v grep | awk '{print $2;}'` Thanks in advance
