Can I map a root domain such as zylker.com, without www, to my Catalyst Slate app?

No. Catalyst Slate custom domains work with subdomains, such as www.zylker.com or app.zylker.com, not with a root domain. The mapping uses CNAME records, and many DNS providers do not allow a CNAME record on a root domain. Map a subdomain, then redirect the root domain to it at your DNS provider.

1. In your Slate app, open the deployment’s Deployment Overview and click Add Domain in the Domain Mapping section.

2. Enter a subdomain such as www.zylker.com and click Next.

3. Add the Step 1 and Step 2 values as CNAME records at your DNS provider, clicking Verify after each.

4. Click Request to request the Group SSL certificate.

5. At your DNS provider, set up domain forwarding from zylker.com to www.zylker.com over HTTPS.

Note: The Catalyst certificate covers only the subdomain you mapped, so opening the root domain over HTTPS shows a certificate error unless your DNS provider serves the redirect over HTTPS.
