Server sent disconnect message type 2 (protocol error): "Too many authentication failures for root" This can easily happen if you are using Pageant and have a large number of keys loaded into it, since these servers count each offer of a public key as an authentication attempt. This can be worked around by specifying the key that’s required for the auth
