Tried to stop the service then do foreground debug:

2024-02-22T11:39:00+08:00 ERRO client/internal/connect.go:187: error while starting Netbird Connection Engine: open \\.\pipe\ProtectedPrefix\Administrators\WireGuard\wt0: This security ID may not be assigned as the owner of this object.

@wizpresso-steve-cy-fan to run the agent in the foreground on Windows, you can follow the guide documented here: https://docs.netbird.io/how-to/troubleshooting-client#windows

I also encountered this problem. I collected some logs according to what you said, but there seems to be no more information.
FYI,everything seems well until i turn on the hyper-v switch in system and use hyper-v recently, this creates some adapter named vEthernet(xxxxxx),i do not know this is matter or not.

OS version:
win10 22H2

Netbird version:
0.26.3

Can you check the output of:

netsh interface ipv4 show excludedportrange protocol=udp

[silencer404]

Thank you for your help,I solve this bug by reboot my PC one more time. I try to reproduce the problem and succeed，steps list as follows：
1.Create or delete virtual adapter.Netbird works well now.
2.Reboot PC and the issue comes.Run netsh interface ipv4 show excludedportrange protocol=udp ,logs are as follows.
3.Reboot PC one more time,the issue solved.

In addition,net stop winnat can also solve this issue.

Yes. I also noticed that if I reboot the PC to the initial state without any WG tunnels, it would work, but subsequent reconnections would fail (so you can't do any inadvertent disconnection like roaming)

Also having this issue, Windows 10. Selhosted.

[timnis]

Same issue with Windows 11 and netbird 0.28.6. Selfhosted.

[pascal456]

• same issue when roaming.
• win 10.
• not selfhosted

also: net stop winnat helped 👍
