I have a node that is using user/password ssh authentication. The node is being reported as offline, and when I try to launch the agent i get:

[02/23/17 15:32:00] [SSH] Opening SSH connection to myUrl:22.
ERROR: Failed to authenticate as myUser. Wrong password. (credentialId:lawrence/method:keyboard-interactive)
[02/23/17 15:32:02] [SSH] Authentication failed.
hudson.AbortException: Authentication failed.

[02/23/17 15:32:02] Launch failed - cleaning up connection
[02/23/17 15:32:02] [SSH] Connection closed.

I have confirmed that the username and password are correct as I managed to login with them manually myself.

What could be the cause of this error?

The root cause is that jenkins user cannot read SSH private key. You should enter private key directly. enter image description here

Instead of logging in, try doing a 

ssh slave command

I am suspecting your login profiles are the culprit. Take a look at this
