nsurlsessiond incredible bandwidth usage every day 1GB

I already tried to diagnose but can not find out what is causing massive downloads of >1GB every day I turn on my macbook.

I have iCloud Drive usage of about 1GB but this is altered just 1 time every week, so no need to fully download that every day ???

Here is a sample output of brctl log -w, please help !!! :
