Home Assistant on Pi 4, Running, but Router Shows Offline

I have a Pi 4 running home assistant and it is connect to my router via ethernet. It has been running fine for several years. Today I noticed that I could not access it (although z-wave commands are still functioning). I checked and my router shows that it is offline.

I have hard rebooted the Pi 4 (unplugged and then plugged back in)
I have rebooted my router.
I have tried a different ethernet port.

Not sure what else to try.

Hi Chris Reeve,

If you are using an SD card, it may have stopped working. I hope you have a backup that is not on that SD card.

I’m using an SSD.

Home Assistant is running. I can verify this because my automations are functioning.

I was able to access home assistant a few hours ago, but now it won’t connect to my router or my router won’t connect to it (it just shows offline in the router interface).

Connect a monitor to your Pi so you can tell what’s actually going on, otherwise it’s a lot of guessing.

Looks like it is my router. Ethernet ports 1-4 are working, but not 5-8.

Sorry for the false alarm.
