Misconfigured DNS preventing discourse-setup completion

I have added manually forum.omaggieconcorsi.online on DigitalOcean DNS control panel.

During setup, when it asks me “Hostname for your Discourse? [discourse.example.com]:” what should I put, only omaggieconcorsi.online?

Because if I put forum.omaggieconcorsi.online and in DNS there is not this subdomain it shouldn’t work, right? Because Discourse would not find this subdomain “forum”.

Sorry, I always have to complicate my life :frowning:
