IPv4 not getting an address

What do I do, I’ve booted raspberry pie 4 with home assistant but I can’t connect to to it because the pie ain’t getting a ipv4 address for the wlan or end 0. Any advice gentlemen

end0 is the ethernet cable connection.
Do you have such one attached?

A ethernet cable would be the fastest way to solve it, if it is not already connected, because there is no setup.
