Hosting private with route53, but no domain connection.

After configuring ineternal alb, I connected to private hosting with A record. Connection with internal alb dns worked fine, but when connecting to the domain (test.example.com) configured for private hosting, an error "ERR_NAME_NOT_RESOLVED" occurs.

In the vpc setting, both DNS hostnames and DNS resolution are enabled, and vpc and hosting are created in the same account. And that domain name is not used by any of the domains I host.

Is there a way to connect to "test.example.com" without "ERR_NAME_NOT_RESOLVED"?
