I ran this command: i created a redirect from port 8080 of tomcat to port 80 and 8433 to port 433 and created "deltapubblicitasrlshop.it.conf" in /etc/httpd/conf.d with this line of code

There was a problem with your DNS in trying to access your CAA record, so Let's Encrypt cannot determine if it is authorized to issue a certificate for www.deltapubblicitasrlshop.it. This issue could be sporadic as it appears to me that you don't have a CAA record.
It also looks like www.deltapubblicitasrlshop.it is using a private IPv6 address (AAAA fe80::3a60:77ff:fea3:4854) and thus Let's Encrypt won't be able to reach it to verify your control of the domain. You will need to either change that address to a public IP address that reaches www.deltapubblicitasrlshop.it or remove it.
Were you meaning to forward 8443 to 443? Your https port (443) is not working at all. You could be really into bulk transfers of articles from one server to another via the Network News Transfer Protocol via port 433 (NNSP), but I doubt it.
With redirect i mean that i add 2 rules on iptables that redirect connection from porto 80 to port 8080 and from port 443 to port 8443. Like this: "iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080"
I am consistently getting a variety of DNS errors trying to look up records for deltapubblicitasrlshop.it and www.deltapubblicitasrlshop.it. Is there a problem with your DNS provider?
We're more than happy to help with your setup, but if Let's Encrypt is seeing anything like what Let's Debug is seeing, that's definitely the primary concern.
If i run "sudo certbot certonly --cert-name deltapubblicitasrlshop.it --apache -d "deltapubblicitasrlshop.it,www.deltapubblicitasrlshop.it" --dry-run" i'll get the same error.
