Checked and hardly find any clue at all. No comments except the word ‘weird’!
After reboot, everything was down. I can’t SSH, but I can ping. I can’t all webUI (portainer, and Nginx Proxy Manager) except Pi-hole, and it’s even weirder that it’s working. 
Anyway, I “killed” it and reinstall everything from scratch. I’m still working on it. Another piece of news is a previous “bug” (Upgrading dietpi: from bullseye to bookworm - #36 by Qlumzy) was replaced by a shorter prompt - “Failed to connect to bus: No such file or directory”. I’m cool, I know it does no harm.
