channel showing but not playing

[oldfart2]

hi
does any one know why the channel called planet knowledge shows in the epg but there is nothing ie- no audio or video seems like alot of folk are saying the same thing, it states that it is a free to air so like why cant anybody view it
i have a gigablue uhd ue 4k but a few of my friends have other types of boxes all the same problem or is it some sort of channel which will only be shown on a particular stb. look forward to some one telling what is wrong or am i wrong.
thanks old fart2

It needs freeview play, so won't work on ViX.
