Verified on cnn.com no ads and i changed settings in my router as follows

Qbit torrent client stopped working
Radarr was having issues

Don't do this. Given multiple DNS Servers, clients are free to use any of them at any time.

Went ahead and removed secondary dns

the upstream dns servers on the right are empty not sure if i need to fill in the info? In pi hole dhcp settings

seeing this issue i added my plex machine IP address in Client group management so that pi hole doesnt use that machine ( am i wrong in understanding this)
