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. I don’t mind listing the domain because it is used for testing only. I routinely destroy it and build it back to test different options and setups.
The IPv4 address brings up the default NGINX welcome screen.
All domains error out
SSL Labs test
IPs detected correctly but in both cases unable to connect to server.
SSL Shopper test
No SSL certificates found.
Both ports open.
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.

You need to open port 443 for IPv4 in your AWS security group (and port 80 for IPv6).
