Describe the problem

Recently I noticed that if I try to resolve peer1.netbird.selfhosted <- example I get:

root@connector# ping peer1.netbird.selfhosted
ping: peer1.netbird.selfhosted: System error

In the resolv.conf DNS file I notice that:

# Generated by NetBird
# The original file can be restored from /etc/resolv.conf.original.netbird

options edns0 trust-ad
search netbird.selfhosted
nameserver 100.71.114.190

Expected behavior

The correct resolution of the local DNS.

Are you using NetBird Cloud?

No, I use the selfhosted version in the cloud on my personal instance

NetBird version

netbird version

root@connector# netbird version
0.59.5

Is any other VPN software installed?

If yes, which one?

Debug output

To help us resolve the problem, please attach the following anonymized status output

netbird status -dA

https://paste.superkali.me/karuhebufi.scss

Create and upload a debug bundle, and share the returned file key:

netbird debug for 1m -AS -U:

Additional context

Add any other context about the problem here.

Have you tried these troubleshooting steps?

Reviewed client troubleshooting (if applicable)
Checked for newer NetBird versions
Searched for similar issues on GitHub (including closed ones)
Restarted the NetBird client
Disabled other VPN software
Checked firewall settings
