switched to a raspberry pi 4 yesterday and for some reason once nest cam see's a person, it crashes all plugins on my end. 
this is what I see right now. it also reported ENETUNREACH. But once I restart it, everything is fine until Nest notices a person. 

the day before everything worked fine on my old raspberry. 
this is a new image btw.
did everything new. 
some hours it just works fine too. 

any idea why? and it is only nest-cam that reports issues. 
all other plugins are fine except once another plug in reported ENETUNREACH as well but then caught itself again until nest-cam said no. 

i am running a pihole on another raspberry. is this the cause for it?
