Samsung soundbar Apple home connection issues

Hi,

After IOS update to 17.4 I cannot add Samsung soundbar HW-Q990C to Home app. It is visible through add accessories/nearby, but there is an error message “Unable to connect to speaker”, “make sure that your iPhone is connected to Wi-Fi”.

I can play music via Airplay now, however in March it was working ok, then after iOS update it didn’t and after another update it started working again.

Situation via iPhone 17.4.1 through Apple TV 17.4 Hub

All devices are connected to same network
