Help with NextPVR

Setup NextPVR, added my IPTV channels and the interface on the server pc works fine, I can watch live tv, read the TV guide, schedule recordings but on an appletv on the same network all I get is blankness using the NextPVR appletv app. Also using the webui for NextPVR in every browser shows none of the ui, it loads the page but there is no content.

Pls pls pls help, seems like in 95% of the way to my ideal setup as NextPVR ui looks great on the server pc
