My Site URL only Works when clicked from the Inside

Question

I've not been too frustrated like this trying to fix something.

I'm almost done moving to SMF, what's left is the readable URL.

I customized pretty URL to match the URL. http://test.example.com/1234/how-to-run

if I click the url within or on the site, it opens and maybe if I copy that url I just opened into another tab it works.

But going directly to the url by just typing it in the address bar redirects to homepage.

If I then visit the url on my site and try again, it works.

I need help please

The problem was from the subdomain. I don't know if it has anything to do with the host. After moving the site to main domain (example.com), it worked fine.
