Headscale: Can't load DERP map (alien.top)
 

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:

root@d12e14ff0f63:/# nslookup

> controlplane.tailscale.com

Server: 127.0.0.11

Address: 127.0.0.11#53

Non-authoritative answer:

Address: 35.156.244.91

Name: controlplane.tailscale.com

Address: 3.73.239.57

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

My mail server log. What is happening? (alien.top)
 

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?

Is a reverse proxy necessary to access remote services when I already use a vpn? in c/[email protected]
[–] [email protected] 1 points 10 months ago

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.
