Your debug log shows that your Pi-hole host machine has assigned the same 192.168.1.102 IP address to both of its network interfaces:

*** [ DIAGNOSING ]: Network interfaces and addresses
   2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
       inet 192.168.1.102/24 brd 192.168.1.255 scope global noprefixroute eth0
          valid_lft forever preferred_lft forever
   3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
       inet 192.168.1.102/24 brd 192.168.1.255 scope global dynamic noprefixroute wlan0
          valid_lft 77738sec preferred_lft 62320sec

This will cause routing issues which may contribute to your observation.

Each network interface should have a distinct separate IPv4 address.
