Seems like you didn’t specify the vlan tag on the controller. Since you are using vlan 1 on the switch side, that is untagged, so you need to define vlan id 0 on the controller, not vlan 1.

Paste the out of these commands

From Switch: sh run int gigxx (Where WLC is conencted)

From WLC: sh interface detailed management
