When attempting to connect to an sftp server it returns immediately with:

Some further investigation reveals that libssh2 is returning with error -43
LIBSSH2_ERROR_SOCKET_RECV.
The easiest way to track this down is to switch over to using libssh2
directly:
Build a debug-version of libssh2, run an example app using plain libssh2 and
see what the libssh2 debug messages say.
If you're using a modern SSH server it isn't unthinkable that your libssh2
version just can't negoatiate a connection with it. You might need libssh2 git
master (or the pending next release, whenever that is...).
