{quote}I doubt that very much - how can authentication be "tried" if there is
no connection ?
{quote}
That is what the symptom may happen.
Connection is ended by Bitvise SSH Server before authentication is tried. And
then authentication starts and fails with timeout. If there is no server-peer,
client-peer cannot have a response from its peer until a timeout.
Anyway, this is just symptom.
