Access EC2 instance via ipv6

0

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: Enter image description here Enter image description here

CIDR is also associated to subnet: Enter image description here

Routing table of VPC: Enter image description here

Inbound security rules: Enter image description here

Instance has an ipv6: Enter image description here

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: Enter image description here

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.
