Kodi live TV

I am attempting to watch live TV with the Kodi Android app over LTE cellular data. I use a dynamic DNS service address to configure the nextpvr add on. As far as I can tell I have everything configured correctly and I see the TV guide populated. When I select a channel to watch TV I see it buffering for a few seconds then I get an error message that says that the tuner is no longer available. If I configure the NPVR add-on inside my LAN over wireless data it works fine. Has anyone ever got this to work with LTE cellular data?
