Airplay LG TV Incorrect Code

I have 2 LG TV. QNED 2023 and OLED 2023, but can’t connect to my LG TV on both my iphone and Imac (Somoma 14.3 last update) also both TV´s had last update.

I´va already done this:

1. Uptodate both TV (QNED OLED 2023) , Iphone 15 and IMAC (24" M1 2021) .
2. Restart 4 devices
3. All are connected to the same Wifi ( Not 5G) , i´ve change to 2.4 G. ( The model of the router is: Echo Life HG8145V5 Huawei.
4. Set to put my own password.
5. The QR code doesn’t work also

The problem is, even recognized the TV´s when i type code (4 digit code ) it keeps saying “incorrect code” even though the code is correct. I tried adding the device to my home app on my phone and it also won’t connect.

The funny thing is when i broadcast a Youtube video , its plays but cannot duplicate or connect via airplay.
