    I get this error on a Mac running the most current version of NoMachine and macOS. The user can log in fine from her old computer running el captain and NoMachine 5.1.44. What happens in the logs on the server its trying to connect to it passes through the key and then the computer itself just closes the connection with out a reason.

    here are the logs from the server side.

    Hi. This error occurs when the client cannot authenticate to the server with the “NoMachine login”, before asking the user credentials for the password based authentication. You can find more information here:

    Configuring authentication in NoMachine
    https://www.nomachine.com/DT12I00037

    If the public key changed, please verify that the client configuration is using the correct private key.
