You can use these instructions to point your domain to your Sitebuilder Plus site:
If you are using Homestead Sitebuilder Plus
If you have multiple sites in your account, you will need to specify which one your domain points to.
Log in to your Homestead account.
In the left navigation menu, click Domains.
Find your domain name in the list and click Change Site Association.
Select your Sitebuilder Plus site from the drop-down menu and click Save.
If this is a new association, you may also need to go to Websites Manager, select your site, and click Publish.
If you registered your domain with another provider
You must update your domain's DNS settings to point to your Sitebuilder site. You can generally find this information in your site editor's dashboard.
Log in to your Sitebuilder account and find the correct IP address and CNAME record needed for your domain.
Log in to your domain registrar (e.g., GoDaddy, Crazy Domains).
Find the DNS Management settings for your domain.
Create a new "A" record with an empty or @ host field that points to the Sitebuilder IP address.
Create a new CNAME record for www that points to your Sitebuilder site.
Save your changes. It can take up to 72 hours for the changes to take effect.
If your domain was already associated
If you suddenly see this error, you may be experiencing a DNS lookup issue or need to clear your browser's cache.
Clear your cache: A stored version of your site in your browser's cache can prevent you from seeing the updated, live version.
Check DNS status: Check the CNAME status with a tool like https://www.ipvoid.com/dig-dns-lookup/ to verify your domain records are active.
Contact support: If the issue persists, contact your Sitebuilder provider's customer support for help.
