Original GitHub issue: https://github.com/netbirdio/netbird/issues/4960

Describe the problem

When running netbird, it is not possible to loopback to the same host using its own netbird domain name. There are no issues when another host on the same netbird network tunnels to/pings that host.

To Reproduce

Steps to reproduce the behavior:

Start and connect to netbird.
Find your FQDN using netbird status.
Ping your FQDN ping <domain>.
Observe that the FQDN resolves to the correct netbird IP but timeouts all packets.

Expected behavior

I either expect the FQDN to resolve to localhost in the internal DNS resolver, or that it is possible to tunnel to your own machine over netbird.

Are you using NetBird Cloud?

NetBird cloud.

NetBird version

0.60.7

Is any other VPN software installed?

No.

Additional context

I am running MacOS 26.1.

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
