Frequently Asked Questions
What does Domain Setup Checker verify?
It checks DNS resolution (A/AAAA records present), HTTPS reachability (valid TLS, no redirect loops), www vs apex consistency, and common misconfigurations like missing records or incorrect CNAME chains.
My domain resolves locally but fails here. Why?
The checker uses public DNS resolvers and makes HTTP requests from our server. If your domain uses split-horizon DNS, is behind a VPN, or is only accessible from certain networks, it may appear unreachable from our infrastructure.
How is this different from DNS Lookup?
DNS Lookup shows raw DNS records. Domain Setup Checker interprets those records in the context of a live website — it also makes HTTP requests, checks TLS, and provides pass/fail verdicts with fix suggestions.
