You're running some nearly decade-old software. Since then, some insecure
hashing and encryption algorithms in many SSH servers have become disallowed.
Try upgrading your libcurl and libssh2 and see if that helps. It might also be
some issue with key availability (e.g., through an SSH agent), but I suspect
it's just outdated encryption.
