Did you really pass "sub.hostname.com" to sftp.Connect, or did you substitute "sub.hostname.com" for the actual hostname you passed. To understand the cause of the problem, I'd need to see the exact string you passed to sftp.Connect. (I'd have to reproduce the problem to find the source of the problem.)
