Here you have. For some reason is not getting an IP:

I think is relevant to the bug that I'm using this unit to start iwd.service:

# /etc/systemd/system/iwd.service.d/override.conf

I remeber adding the override part few months ago due to another bug [1]. For some reason, forcing a disconnect/connect with iwctl doesn't hit the same problem.
