Play media cast nest hub needing Nabu?

Hi,
I’ve setup an automation to play media and to cast a dashboard to my Nest Hub. Before I set it up it said to either have Nabu installed or to have external SSL setup. Now I have the external SSL setup and on the Nest Hub it will say I don’ have Nabu installed. Should this be able to work without Nabu?

Have you found a way to cast something to the Nest Hub without Nabu Casa?

i am doing it successfully. you need to have https setup on your home assistant and dns for it
