I am running the GUI version of duplicacy and trying to add storage (remote synology NAS) over SFTP.
I have created a certificate that I have on the synology and the same one on my machine. The passphrase is correct, because it cries when I have misspelled it.
I get this error while trying to select a Directory:
Failed to create the sftp client: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain
Can someone more skilled than me explain to me what am I doing wrong ? Or at least direct me towards what I could try ?
