SOLVED! Apparently my LG C1 cannot handle 301 redirects correctly. I have emby running behind a reverse proxy that redirects http requests to https. This works fine for everything else but semmingly not for my TV. After I changed the "secure connection mode" setting in emby's network settings from "Disabled" to "Handled by reverse proxy" it started working. Sorry I didn't spot this earlier. Thanks for your support!
