What happened?

I can see that CoreDNS is running:

docker-compose ps:

...
coredns       /coredns -conf /root/dnsco ...   Up      53/tcp, 53/udp
...

Im trying to reach via

• the comms network -> timeout
• my only network -> timeout
• netcat -> Connection refused
• from netmaker container to coredns container -> OK

Ping is ok.

ufw status verbose:

Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), deny (routed)
New profiles: skip

The server is Ubuntu 20.04. The install is exactly the Quick Install. The node is a Debian 10 with systemd-resolved.

Thanks! :)

I figured out: The docker-compose.contained.yml which is comes with the Quick Install does not include dns in PORT_FORWARD_SERVICES.

Setting to PORT_FORWARD_SERVICES: "mq,dns" solved the problem :)
