Suddenly, no DHCP

Group,

I am flummoxed. I have an image that I had been using to connect to a
WPA2 SSID and it has been working for a very long time. It suddenly
quit connecting. This is an Rpi Zero2w with the brcmfmac 43430 chip. I
am running bookworm with kernel 6.6.77. When I set iwd to debug, I get
this:

as you can see, it does not get a DHCP address, but gets an APIPA
address. Any ideas what might be going on? I have tried rebooting the
Pi and also rebooted the DHCP server and restarted the router.
