Those are for FTP transfers (not SFTP).

It is probably an interop problem with the server somehow. If this reproduces
with a recent libssh2 and curl version, it could be interesting to dig deeper
and get some SSH specific details to see what's going on. With this old setup
of yours however, I don't think there's much hope.

That version is 60 releases (more than 8 years) old. Since then, we've fixed
over 2800 bugs...!
