Home assistant companion doesn’t connect on lan

Dear all

I am new to HA and trying to pull out the best of it. Unfortunately, I have reached a limit: the app can’t run on my iPhone when I am at home. I followed all the tutorials but all of them supposed your router accept hairpin ou accept to change DNS in DHCP settings. Both aren’t allowed on mine. So this eliminates adguard, nginx, etc…any other proposal?

Cheers

Can yo use an external URL only?
i.e. the NabuCasa link or a private URL using cloudflared (like this: The Easiest Free Way To Do Home Assistant Remote Access! - YouTube)
