Tunnel don't work without subdomain


I have basic Apache server and I try add Cloudflare tunnel there(with GUI)
In Setup:Public Hostname page if I select subdomain everything works.
I can connect subdomain.domain.test

But if I dont use subdomain I can’t connect to web page domain.test
What I do wrong?

I just want to my domain to point Apache web page


I would like to know if this is possible too. ATM I’m using an A record that’s proxied, however I’d like to close the port forward with the tunnel if possible.

Did you figure this out?
