When a website is reachable through an IPv4 address, DNS is tested and working but all domains error out in Chrome what needs to be checked?
I just moved from Digital Ocean to AWS. My usual setup procedures for the web server I use for experimentation are not working.
I can reach the site through IPv4 but all domains error out and my SSL certificate doesn't show up when tested on SSL Shopper. DNS appears to be working fine, my firewall is open, SSL certificate installed and NGINX running fine. When all the obvious things are working what do I need to check? Or alternately am I missing something really obvious?
This is my setup.
The IPv4 address brings up the default NGINX welcome screen.
Unfortunately all domains error out,

https://example.com
http://www.example.com
https://www.example.com
SSL Labs test
IPs detected correctly on https://www.ssllabs.com/ but in both cases unable to connect to server.
SSL Shopper test
No SSL certificates found on https://www.sslshopper.com/.
In Linux
Both ports open.
firewall-cmd --list-ports
80/tcp 443/tcp
Nginx installed.
Nginx status: Active: active (running) since Fri 2021-03-05 13:48:16 MST; 2h 33min ago
curl localhost:80 returns 301 redirect which is correct.
Lets Encrypt SSL certificate installed.

== UPDATE==
This is what my security console looks like. VPC > Security Groups > [my id]
You need to open port 443 for IPv4 in your AWS security group (and port 80 for IPv6).
