I have had the same issue here, but I dont believe ths issue is with Deja-Dup. In may case I physically chaged the back-up machine (192.168.0.99)
I log into the backup nachine with ssh and ftp Duplicity provides and error: duplicity full Travel/ sftp://sr@192.168.0.99/Backup/ideapad/ The authenticity of host '192.168.0.99' can't be established.
