Apple TV App not loading an my lg oled Smart tv

Hello,everyone,

apple tv app only works when I use it with my ps4 or I put my SIM card in my mobile and use it as a hotspot. Also it works with an older version of my new FRITZ!Box 5g .

but if I want to use it directly on my lg it just doesn’t load and then it.says.network error , can’t find network. Thank,you

cheers and no beers
