I’ve run headscale container on my unraid successful in the past. Today I need to reinstall it from the scratch.

However after spinning up the container, all I got is this error message:

I’ve run headscale container on my unraid successful in the past. Today I need to reinstall it from scratch.

ERR Could not load DERP map from path error="Get \"[https://controlplane.tailscale.com/derpmap/default\](https://controlplane.tailscale.com/derpmap/default)": dial tcp: lookup controlplane.tailscale.com on 127.0.0.11:53: read udp 127.0.0.1:45085->127.0.0.11:53: i/o timeout" func=GetDERPMap url=https://controlplane.tailscale.com/derpmap/default

When I used nslookup command inside the container, it can find derp website:

I’ve used the same config file that I backed up. Anyone has experienced this error?
