Nuking config files to get rid of an existing profile doesn't help, a clean restart greets me with "needs authentication", clicking on "log in" does nothing, there's no account settings pane whatsoever like on macOS, so the tailscale becomes completely unusable.

I am seeing the same thing after the Windows 11 24H2 update at the end of last week on a network where there are no restrictions in place to block tailscale.

Yeah, that state could use some improvement. We've got some work coming up later this year to make that status more informative and precise.

It's not just about observability. The app is not functioning at all in case of a 451.

Also having issues with ver 1.76.0 stuck on starting after upgrading to Win 11 24H2.

ver 1.76.0 on win10 also have this issue

@isotisot, @ls2sl: can you please generate bug reports and post the bug ids here?

For ppl use headscale server, stop tailscale service may help client reconnect:

# privileged
Restart-Service -Name "tailscale"
tailscale up

ver 1.76.3 on windows 11 24H2 also has this issue

Stuck on start issue got resolved when I uninstalled Cloudflare Warp. W11 24H2, TS 1.76.6, Warp 2024.9.346.0. I never noticed any conflict issue before but I can't say for sure if this is new behavior. The hang only seems to occur if Tailscale is started after Warp is engaged.

Have the same issue with startup/reconnect with a custom control plane.

PS C:\Users\me> tailscale status
