Canon R6 stops external video tp Ninja V - Atomos / ATEM mini pro to Mac Book Pro in 1 minute.

I have a new R6, that stops video (power USB C or with fully charged batter) when external connected to HDMI monitor Ninja V - Atomos /  ATEM mini Pro to a Mac Book pro. The sleep is turned OFF. 

Is there a setting or something I am missing? (My 2nd older R6 in another location works fine in similar setup) 

Thanks!

Which is the shooting mode on the camera?  Did you enable “Clean HDMI” output in the menus?
