I've gone through the custom domain validation process, and I've set up a CNAME with my DNS provider, but my website is not working with its custom domain.
(See this article for setting up an ANAME record).
Make sure that the subdomain you have specified in the Hosting Settings screen of Aerobatic is "www" and not "@."
The "@" subdomain will only work if you have set up an ANAME or ALIAS record with your DNS provider, and not all DNS providers support such records.
To handle visitors going directly to mydomain.com (without the www), you would set up domain forwarding / redirect with your DNS provider to forward to https://www.mydomain.com
More information on custom domains can be found in this step by step guide and in our docs.
Any problems, please create an issue or email us and we'll get back to you as quickly as possible.
