DTLS not getting any traffic

trying to figure out why in my APM - SSLVPN configuration no traffic is hitting DTLS virtual :: environment is as follows :

First termination point :

https virtual --> ssl offloading --> Access policy --> connectivity profile --> User connects succesfully --> establishes vpn tunnel interfaces - works fine

second virtual server :

listens on estabished vpn tunnel --> does IP forwarding for all vpn IPs through snatpool IP -> working fine. I see hits.

3rd virtual servers :

dtls (udp 4433) virtual server -> basically terminates dtls forwarding.

However for some reason the dtls is not getting any traffic. The connection profile has the DTLS checkbox already checked.
