Overview
A custom domain is two things: a published project, and DNS records at your registrar pointing your domain at it.
Beginner explanation: DNS is a phone book. You are adding an entry so your domain name resolves to the right place.
Technical explanation: You will typically add an A or CNAME record and wait for propagation. Until propagation completes, some networks see the old destination.
Steps
- Publish the project first.
- Add the domain in project settings.
- Copy the DNS records shown.
- Add them at your registrar exactly, with no trailing dots or extra subdomains.
- Wait for propagation and verify over HTTPS.
:::tip Check propagation from a different network or phone data before assuming it has failed. :::
What to check afterwards
- The domain loads over HTTPS
- Both the apex and www resolve as intended
- No certificate warnings
Common problems
- Records added to the wrong host field. Registrars differ in whether you enter @ or the full domain.
- Old records left in place. Conflicts cause intermittent failures.
- Testing too early. Propagation can take hours.
Where people get stuck
If you have followed the steps and the result still is not right, the fastest path is usually to describe the exact behaviour you expected, the behaviour you got, and any error text, then ask for a fix in one focused follow-up prompt. If that loop is not converging, hand it over.
