cannot access internet radio stations on apple tv 3?

My apple tv is working fine, all apps work, except for the radio app. When i try to use it a message pops up "cannot access internet radio stations, check your network configuration and try again".

I have reset my internet and restarted my apple tv, nothing has worked. Again, all other apps work fine except for the radio help.

Does anyone know how to fix this problem?

Appreciate it.

tks
