Esp32 offline

Hello all

I’m fairly new to ESP32.

I have 4 Everything Presence One multi sensors that have been working fine for the last 3 moths.

Since last week i’m trying to learn how to install frigate.

I installed and started mosquito.

There was an update of HA.

Since then all 4 of my sensors show offline.

All 4 but one sensors still work.

I tried to reinstall esp32 (and update) all 4 sensors

I tried to show the api from the esphome builder and no api is found.
the yaml for each sensor does show an API

my router shows a ip for each sensor
I rebooted HA, the ha vm proxmox and the router
should i delete and reinstall the 4, if so what could have caused thi?

what am i missing to fix this
