Make the www or apex name work over HTTPS on Vercel

headers.redirect.counterpart_unreachable · effort: about an hour

Why it matters

The other spelling of the domain resolves in DNS but fails over HTTPS, so visitors who type it get an error. Either serve it with a valid certificate and redirect it to the main host, or remove its DNS record.

The fix

  1. Open the project, Settings, Domains, add the other name and set it to redirect to example.com.
  2. Set its DNS record as Vercel lists it; the certificate is issued automatically.

The examples use example.com. Replace it with your own domain.

Read the documentation (opens in a new tab)

Scan your domain to see whether this applies to you.
