You should try two things: - Make sure to login with the Administrator account case-sensitive. If your account is called "Administrator", then use an uppercase 'A' when logging in. This case-sensitivity issue is a temporary workaround for a potential security problem in OpenSSH. This will be rectified with OpenSSH 8.0 which allows to login case-insentive again. - If that doesn't help, switch the user running the sshd service from "cyg_server" to SYSTEM (the services GUI calls it "LocalSystem") Cygwin switched the logon method and this method doesn't run under the "cyg_server" account sometimes. However, switching back to "LocalSystem" instead of having to create a special "cyg_server" service account is one of the advantages of the new logon method.
