Access EC2 instance via ipv6
My AWS ec2 instance is accessible via ipv4, but I want to replace it by ipv6. I followed the instructions under https://4sysops.com/archives/assign-an-ipv6-address-to-an-ec2-instance-dual-stack/ to configure ipv6, but it is not working: via ping6 <ipv6>, it says the network is not accessible, same when I enter [<ipv6>] in the browser. When I open the ipv4 address in the browser, it works. Any idea why I can't access the instance via ipv6?
My configuration on AWS:
CIDR associated to VPC:
CIDR is also associated to subnet:
Routing table of VPC:
Inbound security rules:
Instance has an ipv6:
On the instance itself, there is a nginx server which redirects requests to a shiny webserver (https://posit.co/download/shiny-server/). The nginx configuration looks like this:

Hello.
Do you have Nginx configured to listen to IPv6?
https://nginx.org/en/docs/http/ngx_http_core_module.html#listen
For example, if you add "listen [::]:80;" as shown below, port 80 will be able to listen on IPv6.
server {
listen [::]:80;
listen 80;
server_name example.com;
# example setting
}
Also, does the ISP you use support IPv6?
If your ISP does not support IPv6, you will not be able to access it even if you have attached IPv6 on EC2.
