The server may require a client certificate. Or you're using an old
version of curl from when it wasn't supported to attempt to connect
without a client certificate if one was requested. What makes you think
the error is not what it says? Try the latest version, source [1] or
built [2], and also try OpenSSL instead of schannel.
