This log shows that you how have an IP address of 192.168.0.176 on the WLAN interface of the Pi. The Pi-Hole is working as shown on this section of your debug log:
*** [ DIAGNOSING ]: Name resolution (IPv4) using a random blocked domain and a known ad-serving domain
[✓] www.nysubwayoffer.com is 0.0.0.0 via localhost (127.0.0.1)
[✓] www.nysubwayoffer.com is 0.0.0.0 via Pi-hole (192.168.0.176)
[✓] doubleclick.com is 172.217.16.46 via a remote, public DNS server (8.8.8.8)
The problem is in your router and/or clients. After you made this change, did you change the DNS on your router to this IP (and only this IP)? Also, your clients will all need to renew their leases after the router is setup.
