I want to be able to wake up my office computer with ssh when it is in sleeping mode.

Before the last update of Ubuntu 22.04, It was working like a charm. But now my computer is going into a strange deep sleep. I need to be physically there and use the power button to wake it up (it won't work with my keyboard, my mouse, or through ssh).

I tried to change the sleeping settings to avoid the computer going to this mode with

$ sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

But the computer still goes to sleep.
