@88fingerslukee after double checking, the FOG Client does not force log offs; this means that any other user process can stop the log off. This indicates the problem is likely another program on the computer, that or a GPO policy is blocking it.
Could you try running:
shutdown.exe /lmanually on a problematic machine and see what happens?
This command works and logs me out. For some reason it isn’t happening automatically
However, ultimately I would recommend using GPO to handle inactivity log outs. There are some known restrictions with the log out module (https://github.com/fogproject/fog-client#autologout)
Can you tell me how I would do inactivity logouts via GPO? The reason I use Fog for this purpose is because there was never any other way to do this.
