    Hello

    I am trying to connect to my Rock Pi which was working fine. But today after the login acceptance the connection drops.

    I searched the log of the session and i see this error: Io/Io: ERROR! Descriptor FD#16768 out of range in method ‘pipe’ context [A].

    Can u help me pls?

    Hi,

    can you tell us the Linux distro that is installed on the Rock Pi? What desktop environment is it? Steps to reproduce?

    You mention “login acceptance”, does that mean User 1 accepts the request to connect from User 2? What NoMachine product is running on the Rock device? The free version or the Enterprise Desktop?

    Could you submit those logs to us via email? Send to forum[at]nomachine[dot]com. Thanks!

    The Rock Pi runs on Debian 11 KDE and I have the free version of NoMachine on it.                                                                                   
    It was working fine but the last days when I try to sign in from Win11 as a system user without acceptance, it drops the connection after 1 second. Always the same mistake: Error: Descriptor FD# (167_ _) out of range in method ‘pipe’ context [A].

    Thanks for the additional info. So it seems to be a problem on the Player side related to the drivers installed there. Please disable HW decoding. To do that, follow the instructions here:

    Does that help?
