I have followed the guide here : community.Cloudflare.com/t/community-tip-fixing-the-dns-probe-finished-nxdomain-error/42818
but my site still having this error DNS_PROBE_FINISHED_NXDOMAIN on Chrome browser.
Not just my browser, every friend and other pc / lappy using different router and even
gtmetrix dot com couldn’t access my site. Could someone check what’s wrong with my DNS?
