I updated to 2023.6.1 on my supervised installation. Now I woke up twice already to my HA not running anymore. Restarting the Raspi fixed the issues both time. If you run HA supervised, I advice you to wait with the update for some time. For me, I will take this as a lesson and go back to HAOS
Edit: changed version to 2023.6.1
At 4AM this morning the dog woke me up. I noticed that my night light automations weren’t working and so quickly checked HA – found that my recently rebuilt server (Debian) had crashed, not just HA. I couldn’t ping or SSH and so had to force a power down/reboot.
Not sure if it’s the same symptom as yours, but that’s never happened to me before.
