Apple TV 4 problems

Hi,

I’m using plex for 1,5 years and it I have been very satisfied with it. I Have Linux server (AMD A8 , 4GB RAM) for plexmedia server and Apple TV 4 as player. Before I was using Raspberry pi and everthing works ok. Now I bought this apple TV and problems starts… When I watch films (i have mostly mkv) it randomly stops as my network can’t play in original quallty.Than if I wait a few minutes (sometimes more than 5 min.) it starts to work again…This problem I never have with Raspbery pi. Please help me…I can’t watch movies with this problems…

Here are some log files… I don’t understand them…
