Custom Domain publish

The community member is trying to publish their website to a custom domain (www.ps-digital-solutions.de) but is encountering an error message stating that the "custom hostname does not CNAME to this zone." They are unable to use the "@" symbol for the CNAME entry, as their domain registrar (United Domains) only allows the use of the "*" wildcard, which stands for all subdomains.

In the comments, another community member suggests that the issue may be similar to problems encountered with GoDaddy, and provides a link to some documentation on domain connection issues with GoDaddy. However, there is no explicitly marked answer to the community member's specific problem.
