Itunes Twonky Server

Trying to turn on the itunes server functionality go into the hub via 192.168.1.xx and it won’t turn on. Just gives error message bad request was made? Anyone know how to resolve this?

Also cannot turn on the twonky server? What am I doing wrong?

Do it via the HUBs UI.

How do you access via the hub ui? Using the most recent firmware.
