Was there an update on this? I’m experiencing something similar with a new Samsung TV and a Brume GL-MT2500. The wired connection fails intermittently, but when I log into the brume I see everything working. The brume is connecting with WireGuard and has watchcat enabled to double check connectivity, but the problem the TV reports is No Connection when I switch from Tv wifi to TV wired. Unplugging and restarting solves the problem temporarily but the next day I again have no connection when left as wired connection.
