          I just encountered the above error and discovered where I got it wrong.



          The content of id_rsa.pub file on slave3 (which is your manager node) also but be copied over to your authorized_keys file to enable passwordless ssh into slave3. Once I copied public ssh key (id_rsa.pub) into authorized_key, the error was gone. To confirm this, you should run ssh root@192.168.233.134 on slave3 to confirm you are able to ssh into slave3 as root without a password.
