DNS errors and Could not check for JavaScript support in docker instance

[wwe]

hi @Apfelwurm welcome back in the forum

@Apfelwurm

it resolves the public ipv4 and ipv6 without any problems.

Docker doesn’t play well with IPv6 by default… this should not be a problem but more and more client prefer IPv6 and this could result in strange issues. maybe you start with IPv4-only and enable IPv6 once you know the system runs bullet-proof

Look at this topics - there are some hints regarding IPv6

• Apache Docker behind reverse proxy

@wwe

Docker IPv6 enabled /etc/docker/daemon.json

(majority of docker installations will run using IPv4-only - which is default - and only require the 172.16.0.0/12 network)

{
    "userland-proxy": false,
    "ipv6": true,
    "fixed-cidr-v6": "fd00:beef:beef::/48",
    "experimental": true,
    "ip6tables": true
}

regarding the mjs issue - I can not remember anybody reporting this issue with traefik. I know it doesn’t really help to say “it works on my machine” but In my installation I don’t see the issue…

I don’t see any issue on your configs at first glance… consider providing more configs and logs
