sftp is a protocol built on top of ssh. It's the ssh layer where the issue
likely is. OpenSSH disables and removes protocols that are no longer
considered secure and there was (is?) an unfortunate time where the
intersection of protocols supported by OpenSSH and libssh2 was the null set.
If such a combination of versions were used, it would mean no ssh connection
(and therefore no sftp connection) could be made.
