Home Assistant stops being accessible

Hope someone can help me as my Home Assistant keeps going offline and not accessible. It seems to go offline very frequently…at least every hour. I am also starting to see long periods at night when the system is down and it comes back online around 6 or 7am.

I have two instances of home assistant running on my network both managing different sensors and one of them works perfectly.

I have looked through the logs and am seeing many “Home Assistant Core state change” and “Starting system autofix at state running” but I am at a loss whether these are issues or not.

In addition I am seeing error message

 " AttributeError: 'NoneType' object has no attribute 'close'

This IP address is the HASSIO docker.

Home assistant core is 2025.1.2
Supervisor is 2024.12.3

I am floundering and would welcome some direction to resolve!!

I am seeing the exact same error. All of my addons and integrations crashed as well. So far only happened once and a reboot brought everything back.

  • Core 2025.1.3
  • Supervisor 2024.12.3
  • Operating System 14.1
  • Frontend 20250109.0

I am experiencing the exact same problem with the same error messages. Has anyone found a solution to this. I am having to manually restart HA once evry two days. when this happens all of my ICMP integrationsdisplay as offline.
