The meshai container could not resolve external HTTP hostnames (NWS api.weather.gov, SWPC services.swpc.noaa.gov, and the meshview mesh source), failing every poll with "[Errno -3] Temporary failure in name resolution". Docker's embedded resolver (127.0.0.11) forwards to the daemon default upstreams 1.1.1.1/8.8.8.8, which are unreachable from this container's NAT egress (the same egress filter that blocks Docker Hub). The radio link was unaffected because it is an IP, not a hostname. Fix: pin the meshai service to dns: [100.100.100.100], the LXC host's own working resolver (Tailscale MagicDNS). The LXC's /etc/resolv.conf uses only 100.100.100.100 and resolves the public feeds fine, and it forwards public queries upstream. A preflight `docker run --dns= 100.100.100.100 ... getent hosts api.weather.gov` resolved successfully from the docker bridge, confirming the container can reach MagicDNS. Chosen over network_mode: host (more invasive, needs port-binding review) and a host-side daemon.json dns key (affects all containers, lives outside git). This directive is in-repo, git-tracked, and survives daemon reloads. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
