I have trouble with converting chat example to ipv6

[lupin-de-mid]

I'm trying to convert chat example to work in ipv6 only network link to my sources
But mdns unable to discover each other in my lan

Pre check

• first step I checked that my network work ok with ipv4 version. All nodes see each other and transfer messages
  • windos pc x64
  • linux x64
  • linux aarch64

Changes

• I updated mdns init to

            let mut config = mdns::Config::default();
            config.enable_ipv6 = true;
            let mdns = mdns::tokio::Behaviour::new(config, key.public().to_peer_id())?;   

• and change swarm listen address to swarm.listen_on("/ip6/::/tcp/0".parse()?)?;

Results

• All nodes started.. but this all
• So I could ping6 some of address of a node from other nodes
• I could see mdns from other nodes in wireshark on my laptop
• I could observe "new node discovery message" if run two instance of chat app on same host.

Below are logs of startup. remarkable is only on of host with dockers( the last one)

My guess is that this error all related to "docker" interfaces
