Describe the problem

I have a self-hosted Netbird server.

After I updated the client from 0.48.0 to 0.49.0 on Windows, the DNS service went down. I could ping IP addresses, but the DNS resolution didn't work.

To Reproduce

Steps to reproduce the behavior:
Updated the client from 0.48.0 to 0.49.0. Try to ping any domain on the mesh VPN or any public network. Then try to ping IP addresses. Domain ping won't work, IP ping will work.

Expected behavior

Everything should work as expected.

Are you using NetBird Cloud?

self-host NetBird's control plane

I encountered the same issue after updating from 0.48.0 to 0.49.0.
I deleted the registry key HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Dnscache\Parameters\DnsPolicyConfig\NetBird-Match https://github.com/netbirdio/netbird/issues/2895#issuecomment-2483968386, and the issue disappeared after PC reboot.

@WGOS commented on GitHub (Jun 28, 2025):

I did have similar issue on Windows 11 24H2 PC with Netbird 0.48.0. Besides DNS resolution the DNS service itself was consuming up to 100% of the CPU. Though removing registry key was no help
