Hi anonymous user-9128,
Thank you for posting query in Microsoft Q&A Platform.
I got update from internal team.
SFTP in Blob Storage does not support an algorithm that ADF can communicate (diffie-hellman-group-exchange-sha256, diffie-hellman-group-exchange-sha1, diffie-hellman-group14-sha1, diffie-hellman-group1-sha1).
Hence you are seeing that error message while trying to connect from ADF to SFTP on blob.
