Apple TV 4K connection issues with elite suito

Hi, been using my elite suito with my Apple TV 4K and it has been working really well until…

Suddenly today the Apple TV can’t seem to connect with my Elite Suito. Anyone has a similar experience and advise.

(By the way my elite suito software is up to date. I just checked. I also last use the Apple TV and the suito 2 days ago with no issues)
