Does this issue occur consistently or randomly: 
Consistent that video will not stream anymore. It used to stream just fine. Logs don’t show any other errors for Nest Cam
If applicable, what was the last version that worked properly: I don’t know the specific build but it was probably 3 or so months ago that I noticed it stopped streaming. Just getting around to filing a note now.
