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…
