A log from the command with the -vv flag (eg output from rclone -vv copy /tmp remote:tmp)

rclone-v1.35-158-g4652db3β-osx-amd64/rclone lsd seit:
2017/03/06 14:33:52 Failed to create file system for "seit:": couldn't connect ssh: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

And yet ssh remote_server_foo.bar.com works perfectly with the key, i.e. no password request.

Here’s the config:

[seit]
type = sftp
host = remote_server_foo.bar.com
user = kenz
port = 
pass = 
--------------------
Edit remote
Value "host" = "remote_server_foo.bar.com"
Edit? (y/n)>
y) Yes
n) No

After it didn’t work, I edited the config to add a password and it worked again. So I’m fairly sure I configured everything else properly.
