Issues with Netbird client on Windows

[vincent-lg18]

Describe the problem

I want to access my services through Netbird (I'm using Windows 11). In order to do this, I created a route to my pfSense's DNS server to be able to resolve my services domain name (gitlab.mycompany.net for example).

Sometimes, my nameserver isn't available at all :

Nameservers:
  [10.220.220.1:53] for [gitlab.mycompany.net, ...] is Unavailable, reason: 1 error occurred:
        * read udp 172.20.10.7:57553->10.220.220.1:53: i/o timeout

Sometimes, after restarting my Netbird's client (netbird down, netbird up), my nameserver is marked as available:

Nameservers:
  [10.220.220.1:53] for [gitlab.mycompany.net, ...] is Available

BUT, my gitlab web ui is taking a while to load, and my ping to the gitlab server are very strange:

➜  ~ ping gitlab.mycompany.net

However, if I ping it using Netbird's domain name, it works perfectly.

Note that in my client.log, the route is switching from one to another endlessly, maybe this is why it's working sometimes.

Expected behavior

I want to access my gitlab server through gitlab.mycompany.net

Are you using NetBird Cloud?

I'm using a self-hosted NetBird instance.

NetBird version

Both client and server version are 0.27.7

Additional context

It's perfectly working on Linux clients.
