Yes you're right

Fixed it now.

To fix the Issue for anyone doing the guide earlier.

Run to remove nginx from the package list.

sudo rm /etc/apt/sources.list.d/nginx.list

Then run

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

Appreciate your effort for people, I think to use another port instead of 443, and still, it is not working on Irancell!

Are you using VPS?
In my experience Irancell has banned IP of many VPS'es :(

its 50/50 for some Irancell works and for some it does not depending on region / where are live / where you are located.

Test if you can visit your website https://example.com

run to see where it fails.
curl -v https://example.com

Also do the same test on WIFI/ADSL and see if you can connect.
