I have a pi-hole server set up and i tested it on my PC (i set the dns locally on the pc) via ethernet and it works great! however when i set the dns on my router it stops working(websites dont load but facetime and games do?) no matter if im using wifi or ethernet? also if i set the dns to pi-hole on a wifi device it stops working as well?(same problem facetime and games work, websites dont) im using a TP-Link ER605V1
