This is the expected result when pointing your browser at an URL for a domain that is blocked by Pi-hole, e.g. when accessing http://flurry.com.
If this happens for websites that you want to access, you may have to whitelist a domain.
The following topic may help with that:
Your debug log shows your Pi-hole to be operational for DNS via both IPv4 and IPv6.
You've also enabled Pi-hole's DHCP server, distributing its own IPv4 via DHCP with a 7 day lease time, while leaving IPv6 support disabled.
This will likely result in your Pi-hole being by-passed via IPv6, as your router may advertise itself as DNS server for IPv6.
To address this, you'd have to check whether you can disable IPv6 DNS in your router. Note that not all routers may support such an option.
