Why doesn't the page load when I type in my domain URL?

If your home page is published and the DNS is properly configured, it is most likely related to the domain language settings

In HubSpot Settings under Website → Domains & URLs, on the Language Settings tab the "Enable Language Specific Redirects" is checked by default.

This will redirect visitors to the language specific version of the page when available, but it also has the option to add the language prefix to the slug.

This means even if your website only uses one language and is set to English, insted of your URL being https://maka-agency.com it would be configured as https://maka-agency.com/?hsLang=en and unless you are redirecting your domain URL to the language specific page, it will show as a 404 error.
