Your debug log shows that there is not an IPv4 IP address assigned to the ethernet interface, which is what you have Pi-Hole configured to listen on.
The Pi-Hole IP that you think the Pi is assigned (192.168.0.241) is not on the same subnet that you are showing in the DHCP settings on the router (192.168.10.100).
It appears that your DHCP settings on the router should be starting local address 192.168.0.100. Then number of CPE’s 100 (this will give you IP addresses in the range of 100-200.
Then reboot the Pi, and check the router clients list to see which IP the Pi received. Then you make that reservation reserved or static on the router (so it won’t change in the future).
Lastly, run this command to reconfigure the Pi-Hole to use the WAN IP address that you reserved above.
pihole -r and select “reconfigure”
