Can you explain why Apache responds to your "home" page request but nginx responds to the ACME challenge request? Do you have some sort of application firewall or something handling the ACME challenge specifically?
"Home" page server Apache
curl -I6 http://yepezwedding2023.com/
HTTP/1.1 302 Found
Server: Apache
Location: http://13.59.188.206/1/yepezwedding2023/
ACME Challenge is nginx
curl -I6 http://yepezwedding2023.com/.well-known/acme-challenge/Test123
HTTP/1.1 204
Server: nginx
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Pragma: no-cache
Expires: 0
The same responses occur with IPv4 but Let's Encrypt favors IPv6 when present
