Hass.io Homeassistant Core restarts sometimes

Installation Home Assistant OS
1

Hi,

I am running the latest version (15.2) of Hass.io on an MSI Cubi N4000. For about two weeks now, I’ve been experiencing an issue where the Home Assistant Core sometimes crashes, and Home Assistant (2025.6.1) becomes unreachable. All other add-ons continue to work just fine.

I’ve already tried reinstalling it on a new SSD, but the issue still persists.
I haven’t changed anything in my setup (except the SSD) in the past month.

I will attach a log file then I have it.

What could be causing this?

Thanks.

Read the homeassistant.log.1 file in the config folder.
It is the log file from the previous run.

3

I know but I have restarted it two times…

Then you have to wait.

It restarted again :roll_eyes:…

Here is the log:

Could be matter or WLED the problem?
I will try to disable those two.

Looks like you are losing network connection, but the cause is probably prior to the log snippet you have provided.

7

But it makes no sense that my complete home-assistant core crashes???

Edit: I’ve see lots of disconnects in my Unifi Controller. I will replace the ethernet cable.

IOT is a Vlan.

I think it could be a network issue.

You do not have control of you VLAN.
Check your network setup and know that HA is not made to handle multihomed setups.
