    Hello NoMachine Development Team,

    Misleading error message:

    A timeout error occurred while attempting to connect to “192.168.1.250” on port “4000”. The problem could have been caused by a network issue, a firewall or NAT blocking incoming traffic, or an incorrect server address. Please check your configuration and try again.

    The real cause is user inactivity for a period longer than the timeout (approx. 180 seconds).

    How to reproduce the error:

    1. Start NoMachine Player (==> the login window with “Username” and “Password” appears).
    2. Wait approx. 180 seconds without doing anything.
    3. Enter the username and password.
    4. Click “OK” (==> the above message appears).
    5. Click the “Try again” button.
    6. Re-enter the username and password and click “OK” (the connection is established without any problems).

    I suspect that the real reason for this is that the timeout timer starts running when the application is launched. I don’t see any advantage in this design.

    I have used the current NoMachine Player on Windows for connections to Debian. However, I suspect that the problem exists on all platforms.

    Best regards,
