I know this is a very old topic, however I thought I'd add to it in case 
the original author will still get updates and for anyone else running into 
issues who comes across this thread.

For myself, the issue was not having the public key (that was generated on 
the server you're trying to connect to), in the authorized_keys file.

I'll explain a bit further to provide context.  Our Jenkins ID didn't have 
access to publish artifacts out to the folder we needed to push them to 
after doing the build.  In order to get around it, we were trying to setup 
a pipeline script and use sshagent to ssh back into the same server Jenkins 
is running on but with a different user ID.

In order to accomplish this, I logged onto the Jenkins server and navigated 
to the .ssh directory for the user that had the proper folder access.  From 
that location, I generated a new keypair, created the "authorized_keys" 
file (directly within the .ssh folder) and then added the newly generated 
public key into it.  That was the piece we were missing that was preventing 
us from properly connecting.  After that, we created the credential in 
Jenkins with the private key.  From there, we were able to use that user in 
our ssh command and it connected and executed commands properly.
