    Hi,

    When adding a new service node we receive an error "Error SSH communication error: Destination Host <private_ip_address> unreachable.

    In the SSH logs on the "soon to be" node server we have the following:
    Feb 2 13:16:38 <host_name> sshd[1980]: Did not receive identification string from <private_ip_address>
    Feb 2 13:16:38 <host_name> sshd[1982]: Accepted password for root from <private_ip_address> port 38219 ssh2
    Feb 2 13:16:38 <host_name> sshd[1982]: pam_unix(sshd:session): session opened for user root by (uid=0)
    Feb 2 13:16:38 <host_name> sshd[1982]: channel_by_id: 0: bad id: channel free
    Feb 2 13:16:38 <host_name> sshd[1982]: Disconnecting: Received ieof for nonexistent channel 0.
    Feb 2 13:16:38 <host_name> sshd[1982]: pam_unix(sshd:session): session closed for user root

    We only see this issue when using PPA Node Installation as we can establish successful SSH connections between the two servers via command line.
