Apple TV 4K stop streaming every day

My Apple TV 4K 64GB worked fine for a long time, maybe 1,5 year. Moving to a new place and a new router it worked fine for some time but gradually stop streaming during the programs. Happens both on Apple TV+ and other apps. I have done a hard restart, its connected to router with ethernet, speediest showing 100 mb up and down, all other Apple devices like my Mac and my two iPhones can play the Apple TV+ programs just fine. I also can't mirror the Mac and the TV like before, the picture turns black but sound and text are playing on the TV. The Apple TV can be ok for 10-20 minutes but breaks down, no help to restart. Next day can be the same. Even radio apps works sometimes not and other days can play.

WHat can I do?
