Problem with adding new radio station (iradio)

Hi,

There is one radio station (it is called RMF Lady Pank) I want to listen but somehow I cannot add it into the ‘added stations’ menu on the Uniti. I can see it in the vtuner  menu when I log in or type Uniti’s MAC address, I can listen to it on the pc via browser but when I add the station URL (vtuner’s url) my Uniti says that it cannot be played. Is this the case that not all stations are available for Naim stremers?
