Hi.

This error usually happens when you connect using SFTP protocol to server that is not SFTP, and it starts sends invalid greeting back to the client. After some time (or, when he receives 1kb of strange data) client drops connection and returns this error.

Kind regards,
Jasmine.

Hi.

There's not much we can suggest to isolate the issue. It's possible server has changed somehow and doesn't provide regular SSH greeting anymore?
