POA Management Node fails to establish SSH connection to the server mentioned in the error message (Load Balancer server) via RSA keys.
Add content of the
/root/.ssh/id_rsa_lb.pubfile from the POA Management Node to the
/root/.ssh/authorized_keyson the Load Balancer server mentioned in the error message in the failed task.
Check if password-less SSH connection may be established from the POA Management Node to the Load Balancer server.
Important: the public SSH RSA key must be added to the
authorized_keys file on the Load Balancer as single line.
