Any DNS provider — add CNAME for chat.

Use this if your host is not listed in the sidebar, or you use a regional registrar.

What to create

FieldValue
TypeCNAME
Host / Name / Aliaschat (some panels want chat.yourdomain.com — same thing)
Target / Value / Points tocname.vercel-dns.comor the exact hostname ForwardSlash shows in dashboard / email

No http:// or https:// in the target.

Find the right panel

  1. Registrar (where you pay for the domain): look for DNS, Manage DNS, Zone editor, Advanced DNS.
  2. If you see nameservers pointing elsewhere (e.g. *.ns.cloudflare.com), log in to that service and add the record there.

Conflicts

  • You cannot have a CNAME named chat and another record with the same name (e.g. A on chat). Remove or rename the conflict.
  • @ (apex) cannot be a CNAME on some providers; chat is a subdomain — CNAME is allowed.

Verify

  • Online: dnschecker.org → type chat.yourdomain.comCNAME.
  • Terminal: dig chat.yourdomain.com CNAME +short

Then use Go live in ForwardSlash.

Still stuck

Screenshot your DNS list (redact unrelated values), confirm nameservers at the registrar, and support can tell you which panel is authoritative.
