Custom domain verification fails? Check the record name first

A working platform URL lets you keep sharing the site while you connect an optional custom domain. If you already own the name, reuse it. Start with the exact records in your current hosting project.

Read public DNS before editing again

Replace these example names with the zone and record owner supplied by your host. These commands read DNS; they do not change it.

dig NS example.com
dig TXT _verify.example.com
dig CNAME www.example.com

Check the status and authority section. A timeout or SERVFAIL is a lookup failure; an empty answer alone does not establish that the name is absent. NOERROR also needs interpretation: RFC 2308 distinguishes no-data and referral answers.

Namecheap appends the zone in its Host field. For example, use www for www.example.com. Cloudflare proxy mode applies to A, AAAA and CNAME; TXT is always DNS-only. Avoid blanket changes to proxy settings or nameservers.

Finish with the website

Confirm the host accepts the exact hostname, open HTTPS, and test the main enquiry, order or booking action. DNS visibility, domain binding and a working customer action are separate checkpoints.
