Why does homeassistant.local:8123 disappear after a while? (HASOS core)

1

I know there are several similar posts, but I found no comprehensive answer.
This is a core installation on Intel x64, not a VM.

  1. http://homeassistant.local:8123 was working after first installation but stopped working after a few days.

  2. Remote access still works.

  3. If I scan IP addresses I find ‘audreyhomeassistant.broadband’ under 192.168.1.11. http://:192.168.1.11 works OK.

  4. ‘audreyhomeassistant’ is a name I gave it somewhere inside HA; does that affect http://homeassistant.local:8123?

So I have workaround but am still curious why http://homeassistant.local:8123 stopped working and it would still be more convenient to have it back!

I can now answer my own question. I discovered this by connecting a keyboard and screen to the host and restarting …

If you change the name of your host in Stettings → System → Network, then HA automatically changes the domain to that name, with the ‘.local:8123’ suffix. So my system’s name is “AudreyHomeAssistant” and I can acess it through http://audreyhomeassistant.local:8123.

It would be nice if it were mentioned in the documentation on initial installation (in my case Generic x86-64 - Home Assistant) that “homeassistant.local:8123” is just the default name, and changes if you change the network name.

I guess this also anwers my next question: can you run two Home Assistants on one network? Presumably yes, if they have different network names (but I have not tried this yet).

I also notice that the host sets up an ‘observer’ on port :4357 of the same local domain. It’s just a singe web page that says the system is running. What is it used for?

I was struggling with the same issue.
You saved me a lot of time.
