Connect any domain you own to your Rocket app so it is reachable at your custom address with automatic HTTPS. You update records once, and Rocket handles the rest. If you do not own a domain yet, you can buy one directly through Rocket.
You need a Rocket project that has been deployed to the web, access to your domain provider account (for example, GoDaddy, Namecheap, or Squarespace Domains), and a paid Rocket plan. Custom domains are not available on the free tier.

Fix conflicting DNS records

If your domain is not connecting after 24 hours, you likely have conflicting DNS records.
  1. Go to dnschecker.org, enter your domain, and select A as the record type.
  2. If you see multiple different IP addresses, log in to your domain provider’s dashboard and remove any A records that do not point to the IP address Rocket provided.
  3. Wait up to 24 hours for the changes to propagate, then click Verify again in Rocket.
Multiple A records with different IP addresses cause your domain to intermittently point to the wrong server. Keep only the Rocket IP address configured.
