Ssh is not working in node02 server

while installing node_exporter in node02 server, instructions are showing we can ssh into node02 server using root without password but when i try to ssh (from prometheus server to node02)it is asking for password

I think this must be a glitch as I started this lab and could login to node01 and node02. I was able to login from node01 to node02 - you might want to try that. But by now I guess the lab has expired and you won’t see the issue again.
