[BUG] "Host not found (authoritative)"

[Spindyckx]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

in the trackers my trackers show "Host not found (authoritative)"
in the docker logs: Bad Http request method, closing socket. IP: ::ffff:172.19.0.1. Method: "CONNECT"

no firewall is blocking port 6881, the port is forwarded in my router.

when opening a shell in the container it cannot resolve google.com or any other site.
this was fixed by manually changing the /etc/resolv.conf file:
I changed the nameserver 127.0.0.11 => nameserver 8.8.8.8 (or any other upstream dns server)

Expected Behavior

it should be able to resolve sites.

Steps To Reproduce

docker-compose up -d

Environment

DSM 7.2.1-69057 Update 5
Docker version 20.10.23, build 876964a

CPU architecture

If you're needing to edit the resolv.conf file within the container, that would imply an issue with the deployment of the container as that's docker's internal dns which consumes your hosts dns.
