Can you also provide the output of your flexconnect group:

You will need to setup a FlexConnect Group or modify the default flex group, under WLAN VLAN Mapping tab you need to:

- Enable VLAN Support and enter your native VLAN, VLAN 100

- Map your WLAN ID, (WLAN 1) to VLAN 10

- Map your AP to the Flex Connect Group by going under the General Tab depending your WLC version you should see "FlexConnect AP" where you can go and add the AP.

And 8.3.143.0 is quite old code (went end of software maintenance last year) so you might want to think about getting onto at least 8.5 code - see https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html and check your hardware support in https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html and the release notes for the chosen release. If you need to stay on 8.3 then at least think about getting onto latest 8.3.150.x Escalation build.
