If you see a 169.254. x.x address, it means that the DHCP server is not reachable. The PC will not work because there is not a router to or from that PC. Troubleshoot this by finding out why the PC cannot see the DHCP server.

APIPA only occurs at 169.... when dhcp is not working, so dhcp scope is exhausted

Which ethernet jack? Of the AP? God, there could be vlan trunking configured and you are plugging in a PC to the same jack which connects the AP? And what if there is passive-POE? But yeah, from the options it looks like DHCP exhaustion. Because other options does not make sense. But the main red-herring is that the AP is restarted. Before restarting it was fine. Yeah, it could be DHCP exhaustion because the device will do a DHCP Discovery again after associating again to the AP.
