No supervisor connectivity

You can’t configure much in Docker. I disabled IPv6, no difference. I also disabled interface end0. My working HA has that disabled. Not sure of the result yet, but not optimistic.

Have you tried rebooting it?
Sometimes it will pickup new changes.

Power-cycled many times, including after disabling IPv6 in Docker (instructions say it is required). It has been a few minutes since I disabled interface end0 and the logging hasn’t displayed a failed log message. It is doing something but I don’t know what.

That is where I would focus on.

TY. Heading to bed…

I got a second HDMI micro cable so now I can view both the working HA and new HA together. I found that output from ‘net info’ has a line labeled ‘host_internet’. On the working system it is ‘true’. On the non-working/new system it is ‘false’. Does anyone know if this is something that I can set or is set by the code?

There are also some other differences. In the working HA, the interface ‘end0’ is disabled. So I have disabled it in the non-working/new HA. Also, at the bottom of the ‘net info’ display is a line labeled ‘supervisor_internet’. On the working HA it is ‘true’. On the non-working HA it is ‘false’. That one seems obvious.

The connected devices on my router showed 2 connections from my new HA. One was the static IP addr that I assigned but that was tagged as wireless/5GHz. The other address was one assigned by my router and marked ‘wired’. When I changed my HA ipv4 address from a static address to the address assigned by my router it immediately started preparing Home Assistant. Simply plugging in the ethernet cable wasn’t enough.
