How do I enable ipv6 with Nginx
Hello,
EDIT: read that the flag is not there since 1.11.5 the flag was removed and should auto defect support for IPv6, I have listen [::]:80 in my conf file but going to the IPv6 address listed on my linodes page in cloud.linode.com it does not work I have allowed ports 80 in UFW and v6 is listed in the allowed.
I installed Nginx using
Installing Prebuilt Debian Packages
on my Debian 9 Linode
but it does not seem to have IPv6 support when doing Nginx -V this is the output everything I found on google says it should be enabled?.
Does anyone know what's going wrong and how I can enable IPv6 support?

FWIW, my nginx -V (installed from packages not built from source) doesn't say anything IPv6 either:

And yet, it does definitely listen on IPv6.
My server
listen 443 ssl http2;
listen [::]:443 ssl http2;
Suggestion:
Instead of troubleshooting by going to the IPv6 address - first check if nginx is listening on IPv6, this is as direct as can be:
netstat -tlnp

As you can see, both report nginx listening on "all" address (0.0.0.0 for IPv6 and [::] for IPv6) on ports 80 and 443 (and there are some other services).
