Cast to nest one camera gets blacked out

When casting to google nest. One camera gets blacked out. It works for like 1-4 seconds and then it just get a black picuture. This does not happen on a browser on a computer but only on the nest. If I choose auto instead of live it displays the camera but not live ofc. And live is what i’m after.

What should I try to modify?

Any suggestions?
