Unable to setup SFTP, Get error ssh: handshake failed:

Failed to retrieve storage information

ERROR Failed to load the SFTP storage at sftp://pooze@10.0.0.8/datadir/: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none], no support methods remain

Tried both password and key authentication, both produce the same error.

Problem automagically resolved its self.

Could have been a temporary network issue.
