If everything is configured correctly, it should take a few minutes for your production Zup to start responding to traffic on your custom domain. On the other hand, if a misconfiguration (typo) occurs and you need to make changes, Cloudflare could take up to 4 hours to retry the verification. Please be patient if this happens.
