UBG2 -> Streaming Bridge Talkback

G'day, has anyone got the UBG2 & Streaming Bridge to send talkback from director to camera?
Our setup is all on the same subnet, camera vision is appearing on the atem no problem, tally & CCU are working. So far no matter what I try, simply cannot get talkback to the camera operator.
I am aware the talkback is unidirectional, not a problem.
There is no routers in the way, so no port forwarding required.
Both camera and Streaming Bridge are on same subnet.
If I plug camera into ATEM with SDI everything functions normally.
Thanks for any help.
