Unusual traffic to .nflxvideo.net to use 4GB pre day

Archive HASSbian

Hi, everyone,

When I was checking the internet usage from router. I found my raspberry Pi which installed hassbian used around 180MB every hour. It was 4GB pre day. Actually everyday. And each hour records are really average.

My router showed the usage from hassbian is connected to Netflix. But I didn’t install any related software. Only Home assistant is running there. And I tried to use nethogs and looking for the source, I didn’t observed any program was download or upload like that much. Is anyone experienced similar case?
