DNS lookup started failing today but only for one website.
Results return as 0.0.0.0 and page loads in browser report DNS_PROBE_FINISHED_NXDOMAIN
Compare the results of a DNS lookup against router vs. against the external DNS server directly:
ipconfig/flushdns
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.

And here are the results of a DNS lookup inside the firewall interface:
I conducted further troubleshooting with security and firewall rules but saw no other relevant data to report. The website works fine from my cell phone when NOT connected to Wi-Fi.
The important error seems to be the failure to return the correct address instead returning 0.0.0.0. Other names will resolve to IPv4 addresses or combination of IPv6 and IPv4 addresses and one can reach the website. This address resolved just fine until sometime late yesterday.
