For some reason HA on my Pi4 keeps setting the route metric for my eth0 connection to the router to 2000, which effectively breaks it’s internet connection: Ping failing “Destination Host Unreachable”. This all started happening after I upgraded my OS from bullseye to bookworm… any ideas on how to fix this? at least once a day I have to go in and delete then add the route again so it has a reasonable metric. This still happens whether I set a static or dynamic IP.
