Out of Box Installation - not working

Hi all. Got an HA Green out of the box, trying to install it, but I fail badly.

After 1/2 day of trial and error, I am not able to move further than to following repeating log error(s):

2025-12-25 16:59:41.192 INFO (MainThread) [supervisor.docker.interface] Downloading docker image ghcr.io/home-assistant/green-homeassistant with tag 2025.12.4.

I plugged into the console and started to learn the CLI commands, and was able to observe, that the network settings keep changing, IPV4 being as ready true/false randomly.

I changed the IP in my router to a static IP, which sometimes reflects also in the “ha network info” screen. And sometimes again not.

Received also the “low voltage” error, so installed a 2032 battery, just to be sure (however that meanwhile quite errodes the “out of the box” experience).

Thanks for help

Check your DNS settings, and you can also try another cable and / or another port.

Thanks, meanwhile tried to change the cable and that might have helped. Fingers crossed.
