Mojave/mac mini don't recognize ethernet at night, after 06/05/2019

Since yesterday, my mac mini with Mojave 10.14.5 don't recognize my ethernet and web, just at night, after some sleep time. I'm suspecting of some update have been instaled in this last few days.

Looking of system information, I saw "Gatekeeper Configuration Data", version 167, and "TCC Configuration Data", version 17,0. This is the lasts updates. Does someone know something about this, or having the same problem??
