FortiGate managed FortiSwitches with Unifi accesspoints

Hello,

I have an issue with my set-up.

I have a FortiGate 40F connected to 1 FortiSwitch 124F and a FortiSwitch 108E-PoE.
My FortiGate (7.4) is physically connected to the FortiSwitch 124 on port 2 and the FortiSwitch 108 (both running 7.4) is connected to port 1. The Fortigate can see both switches, both switches are connected and authorised through the fortilink.

I can manage VLANs and ports on both switches.

I have also 3 Unifi UAP6 Pro accesspoints managed by a Unifi controller on a local server. Those accesspoints used to serve 4 VLANs. I'm saying "used to" because lately I replaced my old Zyxel switch with the FortiSwitch 108. On the first 3 ports I've connected the 3 AP's because of the PoE. I've added a trunk with those 3 ports, allowing all VLANs (1-4094), however no traffic is flowing over the AP's. The first traffic I would like, is to receive DHCP addressing, provided by the Fortilink interfaces.

Can someone provide some guidance?
