I had three profiles that where running SFTP exchanges.
Yesterday the remote sftp server has disabled SHA1 (SSH MACs) to avoid a recent vulnerability, and left only the following
SHA2 256 / SHA2 512
Now The profiles are failing. this is what i get from the connection test

Re: SFTP Key exchange failed (SHA2)
Try changing the FTP engine under the profiles's FTP settings.
