What I have changed since installing Pi-hole:
I tried some hints from others, but nothing worked. I only touched minor things like chown to less security.
You have two active interfaces on the Pi-hole, WiFi and ethernet:
*** [ DIAGNOSING ]: Name resolution (IPv4) using a random blocked domain and a known ad-serving domain
[✓] webapp.letomarketing.net.zooplus.it is 0.0.0.0 on lo (127.0.0.1)
[✓] webapp.letomarketing.net.zooplus.it is 0.0.0.0 on wlan0 (192.168.86.49)
[✓] webapp.letomarketing.net.zooplus.it is 0.0.0.0 on eth0 (192.168.86.50)
[✓] doubleclick.com is 142.250.69.206 via a remote, public DNS server (8.8.8.8)
Pi-hole is configured for the WiFi interface, and that appears to be the active interface:

Thank you! i ran pihole -r and reconfigured for eth0. I was able to easily get to the admin screen. FYI Just finished with paypal: "You sent a payment of $52.54 USD to Pi-hole (support@pi-hole.net)"
