Cannot connect to http://homeassistant.local:8123/

[dim sedge]

I just received new Home Assistant Green. Switched it on and probably interrupted the initial start up. So I cannot reach configuration app over browser. After some research, I figured out:
i cannot connect also over <ip>:8123
i can reach observer and everything is great
interface end0 has ip from dhcp (192.168.xxx.xxx)
docker0 has another ip (172.xxx.xxx.xxx)
ha core info output:
arch: aarch64 audio_input: null audio_output: null backups_exclude_database: false boot: true duplicate_log_file false image: ghcr.io/home-assistant/green-homeassistant ip_address: 172:30.31.1 machine: green port: 8123 ssl: false update_available: false version: 2025.12.5 version_latest: 2025.12.5 watchdog: true
If I understand it correct core is running in docker and cannot be accessed from home network
ChatGPT means only solution is to flash and reinstall OS. Didnt it till now. Are there other possibilities?

i restarted core and found this messages in supervisor logs

which message did you find in supervisor logs?

a reflash is not a bad option.
you can also try running :
ha core rebuild
followed by a power cycle

Finally I had to reflash. It went well.
Issue was, that I interrupted initialisation process, and docker didnt received any IP from router and took one internal. I couldnt change, reset or something else it anymore.

I am asking me now what will happen if I have to change a router. Probably docker will keep first IP received and I have to flash again. Is it correct? or will it get a new one and I had the issue because of initialisation interrupt?

[dark trout]

as long as you have it set to dhcp then you should be fine. the docker network ips are not the external network ips.

ok, thank you. I think I will close the topic
