    I updated my install to version 6.8.1 today and I am now getting a few errors including a PAM error when trying to log in.  I am able to login via ssh with the same credentials I am using for the NoMachine login.  The errors I’m getting are below:

    Hello munsen70,

    Can you show us the output of following command ran in terminal on affected machine:

    stat /Applications/NoMachine.app/Contents/Frameworks/bin/nxexec

    You can also try to reuse SSH PAM configuration with NX protocol.
    To do so, run as root in terminal:

    cp /etc/pam.d/nx /etc/pam.d/nx.bak
    cp /etc/pam.d/sshd /etc/pam.d/nx

    Does it solve the issue?

    I didn’t change anything, but as of this morning I’m able to get into my machine and no longer getting any errors.
