Are you trying to use a public key? The error message says that it's not
available:

If you're using a password authentication, are you supplying the correct
user name and password?

There is a known issue with libssh2 that causes authentication to fail
randomly about 1% of the time (bug #1832491), but that's unlikely to be
the problem here if it happens consistently.
