Can I not use top-level domain names for installation?

After I installed it using a top-level domain name, I cannot open the URL. Can this program only use second-level or third-level domain names?

It can work on a top-level domain, I have a discourse on a .com domain.

But this doesn’t help explain what is happening with your installation.
