Tunein playing on PC but not on LG



Hi Wonder if anyone can help, I have loaded custom URL's on Tunein. I have loaded Tunein on Plex Channels and they work perfectly when I playing through my PC Chrome interface. I try play them through my LG TV using the Plex app and it fails to play with an error. Shoutcast works fine on LG TV.

Is there something else I need do or have missed. Or can someone give me advice regarding playing custom URL "Internet Radio Stations" using Plex ---- for Example http://ice9.securenetsystems.net/WGMP

P.S. Just checked worked fine on my Samsung TV
