I'm using NetBird VPN on a MacBook Pro with Apple M4 chip running macOS 15.5. I’ve tested both the latest NetBird version and some older releases.

After connecting to the VPN, everything works fine for a few minutes, but then DNS resolution fails intermittently — I cannot access protected/internal pages. After some time, DNS starts resolving again without any manual intervention.

Steps to reproduce:

Connect to VPN using NetBird.

Access protected/internal pages.

Wait a few minutes and observe DNS failures.

After some time, DNS resolution recovers on its own.

Any ideas or suggestions on how to fix or debug this?
