[IPv6] docker is not connecting to IPv6 network

I am new here, plus i am way more a Windows guy but i am trying to work with docker (learning it). I have setup a few dockers, it works. But now i have got something that i cannot get to work. I due apologize for any stupid/easy questions. Linux/docker isn’t a 100% my world (yet).

I did the first 4 steps:

So i add this:

{
“experimental”: true,
“ip6tables”: true
}

to my empty /etc/docker/daemon.json file. i rebooted.

When i look in Portainer i am seeing ip6net as a network. But this adguard docker is not using it, but i dont know why. Any ideas why this network is not being used by this adguard docker?

`
