Describe the problem

I can access the dashboard when my peer is not connected to the server, but as soon as I connect a peer, I can no longer access the web interface / resolve the hostname of my netbird server.

To Reproduce

My peer isn't connected:

> netbird status -d
Peers detail:
Daemon version: 0.27.3
CLI version: 0.27.3
Management: Disconnected
Signal: Disconnected
Relays:
  [stun:vpn.mycompany.net:3478] is Unavailable, reason: dial: failed to listen: dial: dial udp: lookup vpn.mycompany.netsh: no such host
  [turn:vpn.mycompany.net:3478?transport=udp] is Unavailable, reason: create client: lookup vpn.mycompany.net no such host
Nameservers:
FQDN:
NetBird IP: N/A
Interface type: N/A
Quantum resistance: false
Routes: -
Peers count: 0/0 Connected

And I can access and resolv the DNS name of my netbird instance:

> Resolve-DnsName -Name vpn.mycompany.net

Name                                           Type   TTL   Section    IPAddress
----                                           ----   ---   -------    ---------
vpn.mycompany.net                                 A      342   Answer     X.X.X.X

But as soon as I connect my peer:

> netbird status -d
PS C:\WINDOWS\system32> netbird status -d
Peers detail:

 wiki.vpn.mycompany.net:
  NetBird IP: 100.73.198.88

NetBird IP: 100.73.171.160/16

Quantum resistance: false

Peers count: 2/2 Connected

I can't access my dashboard:

> Resolve-DnsName -Name vpn.mycompany.net
> # see there's no output

Expected behavior

I would like to be able to access the netbird web interface even if I have my peer activated.

Are you using NetBird Cloud?

I'm using a self-hosted netbird instance. I have a domain name pointing to the public IP address of my server hosting Netbird services.

NetBird version

> netbird version
0.27.3

Additional context

As a workaround, I declared a nameserver pointing to google's DNS resolving vpn.mycompany.net

Though, the internal DNS isn't working anymore:

> Resolve-DnsName -Name vpn.mycompany.net 

Name                                           Type   TTL   Section    IPAddress

Hello @vincent-lg18 the issue happens because the self-hosted domain for your peers matches the management domain.

You can review the configuration and set the --dns-domain= to a different domain name, e.g., hosts.vpn.mycompany.net, and restart the management to distribute this configuration to your peers.

Hello @mlsmaycon
Yes it's working fine now, thank you! I didn't see it anywhere is the doc. I could have missed it, but if I didn't, you should add it somewhere.
