After you add a custom domain and its DNS record, Capsulink checks the record automatically. Most domains are verified within 10–30 minutes; in rare cases DNS changes take up to 24 hours to spread.
Check it right away
Open Settings → Custom domains and click Check DNS now next to your domain. If the record is correct, the status changes to Verified.
"Verification Failed" — the usual reasons
- The record points somewhere else. A root domain needs an A record to 91.241.66.74, a subdomain a CNAME to cname.capsulink.com (or the same A record). Capsulink shows what it found instead — compare it with your DNS settings.
- Two records for the same name. An old A record (for example, from your hosting) is still there next to the new one. Remove or edit the old record for this name only.
- An AAAA (IPv6) record for the same name points to another server. Remove it for this name.
- Cloudflare proxy is on. Set the record to DNS only (grey cloud). See Custom short domain configuration with Cloudflare.
- A typo in the domain name in Capsulink or in the record's host name.
After fixing the record, click Check DNS now again — there is no need to delete and re-add the domain.
SSL (https) error
The SSL certificate is issued automatically shortly after the domain is verified. If you see a certificate error for more than an hour after verification, the most common reason is the Cloudflare proxy (orange cloud) — switch it to DNS only.
Will this affect my email or website?
No, as long as you only add or change the record for the short link name. Don't delete MX or TXT records — your email keeps working as usual.
