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\\": 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?
There are a lot of connections from this IP: 185.36.81.40. Is this IP trying to use my mail server as a relay server? What should I do to get rid of this connection?

If you use your services for yourself or family, you don't need a reversed proxy, but to share some of your services to the public or your friends, you need a reversed proxy in order to let them use/remember your domain name without knowing your public ip given by your isp; for convenience and security reason.
