ipv6 not supported on pango?

[VinterSolen]

It seems users cannot connect to/via my pangolin with ipv6.

So i bounce around a few sites and checks ( https://ipv6test.wcode.net/ and https://ready.chair6.net/ ).

Both sites claims that ipv6 is not supported on the server (pango is on a vps with both v4 and v6 ip)

Server runs UFW, and ufw status shows

22/tcp                     ALLOW       Anywhere                  
80                         ALLOW       Anywhere                  
443                        ALLOW       Anywhere

Am i missing something in my pangolin in docker setup?

if i edit sudo nano /etc/docker/daemon.json and enable ipv6, nothing works

    "ipv6": true,
    "fixed-cidr-v6": "my_ipv6_Address_here/64"
