Add SFTP remote backup destination failed

I’m having this error trying to add a remote sftp server as backup destination. All login data is correct.

Operation Failed!

Host ... found: line 1

/root/.ssh/known_hosts updated.
Original contents retained as /root/.ssh/known_hosts.old
EOF [sendKey]

Any idea what is happening?
