Sophos Accesspoint to VLAN

I have a issue connecting Sophos AP to specific VLANS (Bridge to AP VLAN). 

The issue is that I am not able to get any IP from the DHCP when connecting to the configured access points. The AP is connected to a switch, but I have even tried to connect the AP directly to the Sophos Firewall without any luck. 

Any ideas what I am doing wrong? Does the switch port the AP is connected to need to be in trunkmode? Tagged? "Both/Hybrid"? I feel have tried everything.
