[supervisor.homeassistant.core] No Home Assistant Core response, assuming a fatal startup error #5797

Codelica · 2025-04-01T17:06:39Z

Describe the issue you are experiencing

Ever since the "new" backup system was released I haven't been able to "complete" a backup (auto or manual). While the supervisor logs seems to show the backup is complete, and I see the backup in the lists, the spinner never stops and I can't attempt another without restarting Home Assistant. It's as though Supervisor isn't able to message Home Assistant about being done (guess). It's happening on two independent HA installations I run.

The one error I see come through in the supervisor logs that seems suspect is:

2025-04-01 10:46:55.109 ERROR (MainThread) [supervisor.homeassistant.core] No Home Assistant Core response, assuming a fatal startup error

I've tried ha supervisor repair and a reboot, but that didn't seem to help.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Steps to reproduce the issue

Unfortunately I'm not sure. But seems to have started with the new backup system release. It's happening on two independent HA installations I run.

Anything in the Supervisor logs that might be useful for us?

Seems suspect:

`2025-04-01 10:46:55.109 ERROR (MainThread) [supervisor.homeassistant.core] No Home Assistant Core response, assuming a fatal startup error`

Additional information

All info here is from one of the two systems having the issue. It's a very simple installation compared to the other system, and I can experiment as needed on it.

So this comes down to having http.server_host set on my HAOS installs. While this "should only be used on a Home Assistant Core installation" per the docs, there doesn't seem to be any other way to control what interface/ip will host the UI.

I am setting it to a private interface/ip on a vlan which has all my applications that are proxied via NGINX. Ideally I'd like to set it to be that vlan IP and 172.30.32.1 which Supervisor uses to reach Core (per what I see viaha core info) but even http.server_host won't take multiple entries.

So it seems my only choice is to bind to 0.0.0.0 with HAOS unless there is some other route, of a different IP for Core can be set in some way?

Pro100x3mal · 2025-04-04T13:33:54Z

I have exactly the same problem for several versions in a row. Neither automatic nor manual backup works. There is a constant process of creating a backup copy until HA reboots. It does not create a copy either on the local device or in OneDrive.

I'm betting you have a similar situation. Are you setting http.server_host to limit where the Home Assistant UI/API runs?

You an see what IP and port Supervisor it trying to reach for core via ha core info where it shows ip_address and port. If the UI/API isn't running on that you'll get the errors we are seeing.

In the end I had to get rid of my http.server_host setting and just firewall things so that it's only exposed where it should be, as I couldn't find any way to give multiple address or change what Supervisor uses to reach Core.

Pro100x3mal · 2025-04-04T15:04:16Z

@Codelica I don't have HAOS. I have home assistant supervised.

Codelica · 2025-04-04T15:10:06Z

Yes, I saw that. But the Supervisor container still needs to communicate with Core and is failing. Are you setting http.server_host ? If so I'm betting backups will "work" if you remove that.

Pro100x3mal · 2025-04-04T15:20:03Z

in my configuration.yaml:

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 127.0.0.1
    - ::1
  ip_ban_enabled: true
  login_attempts_threshold: 5

Codelica · 2025-04-04T15:45:33Z

Interesting. Doubtful Supervisor has been banned :) I guess it still may help to see what address it's trying to reach Core on via ha core info and then see if it's actually listening on that via something like netstat -plnt |grep :8123

Pro100x3mal · 2025-04-04T15:54:14Z

Indeed, I disabled ufw on my Raspberry Pi and the backup is created without problems. Before that, there were errors in the Host log:

2025-04-04 15:40:14.276 homeassistant kernel: [UFW BLOCK] IN=hassio OUT= MAC=xx:xx:xx:xxSRC=172.30.32.2 DST=172.30.32.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=46770 DF PROTO=TCP SPT=49710 DPT=8123 WINDOW=64240 RES=0x00 SYN URGP=0

But I don't want to disable the firewall. I wonder what I need to add to the http section in that case?:

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 127.0.0.1
    - ::1
  ip_ban_enabled: true
  login_attempts_threshold: 5

Pro100x3mal · 2025-04-04T16:01:53Z

added sudo ufw allow 8123/tcp and everything works. But now I need to think about the security of this action, since I have a public IP and HA works behind a reverse proxy Nginx on RPi for remote access to HA. RPi in turn is in the local home network behind my router, on which port forwarding is configured.

Pro100x3mal · 2025-04-04T16:33:18Z

Solved the problem by adding the following rules:

sudo ufw allow in from 192.168.1.0/24
sudo ufw allow in from 172.30.32.0/24
sudo ufw allow in from fe80::/10
