Hi, i'm using default installation of pihole using OpenDNS us upstream DNS provider in the last 3 months everything works perfectly but now i'm stuck can't update or install from play store on my android phone unless i changed from pihole DNS then it work perfectly.
I tried restarting/updating/rearing/clearing cache of pihole without any help, the problem is that pihole is not blocking any of google domains is just keeps sending those connectivity checks without any help (Pihole doesn't block them).
I've changed my upstream DNS to google same problem.
Can someone suggest to me a solution?
