I had an odd thing happen today. HA wasn’t responding, no pings, no UI, nothing. After a few restarts and nothing improving I pulled the Pi4 to my desk and fired it up so I could see what the console was saying and everything ran clean. When I checked ha network info I could see that my eth0 was completely disabled, as soon as I reconfigured it for DHCP again it came right up and all was right in the world.
I’m wondering how it could have disabled itself and if there should be something that I need to look at to prevent it in the future. This is the only time this has happened so I don’t know if it was a fluke or it’s starting to develop an issue. I could write a shell script to execute periodically to check if the interface is disabled and run the necessary HA commands to fix it, but that seems like overkill.
The logs were 100% clean until the network went away, then of course anything that relies on the network was complaining like crazy, and it’s been running clean ever since I re-enabled the interface.
