Problem: Screen mirroring from macbook to appleTV

I have 1 week problem connect from MacbookAir M1 (Sequoia 15.2 (24C101)) to AppleTV (A1625 (32GB)) (TVOS 18.2.1) . Error response is: Could not connect to Apple tv. The wifi is similar. Connecting from iPhone, or iPad is successful. Next problem is screen saving (my photos) during music play. Doesnt work.
