Answer 1

It seems your LAP AP is not getting the iP of the management subnet and LAP is in different subnet than your management IP.
Please try keeping the static IP on the LAP and then try joining it to the controller first and later on keep it on the DHCP.
when AP is plugged into a switch, the switch port needs to be access with the right VLAN allowed
