Original GitHub issue: https://github.com/netbirdio/netbird/issues/2173

Describe the problem

Netbird interface keeps flapping up and down on Windows and Linux.

To Reproduce

Steps to reproduce the behavior:

Install Netbird
Watch it flap by constantly refreshing network interfaces at the command line.

Expected behavior

I didn't expect v28 to blow everything up. It's preventing me from getting to my services.

Are you using NetBird Cloud?

Yes.

NetBird version

27.10 on Windows but it does the same no matter which version I install. 28.2 on everything else. Tried 28.2, 28.1, 28.0, and now 27.10 on the same Windows 11 PC but it's the same all over, constantly reconnecting to peers and the WT0 interface keeps disappearing and reappearing. Same behavior on all my Netbird clients.

NetBird status -d output:

If applicable, add the `netbird status -d' command output.

No. All it shows is a list of peers but it's constantly reconnecting to them all.
