Nextcloud on public networks

Im searching the boards to no avail.

I have newest version of Nextcloud running on Nginx with mysql on a raspberry pi. Its installed and optimized through dietpi OS.

The cloud works great… at home.
I can’t seem to get any response on any network besides locally. I’ve done my best editng the .conf files and nginx avaialable-sites, and I’ve forwarded ports 80 and 443.

What am I missing.
I’m on my phone away from my residence but ill post full text of my config files as soon as I can.

Do you have a dyndns-service witch points to your homenetwork?
Did you open port 443 in your router to point to the pi on witch your nc runs?
