Occasionally i have come accross a Tailscale client that does not initially want to display the log in page.
I originally also tried running CLI commands like “tailscale up –authkey xxxxxxxxxx” as well – it seems to hang.

So when CLI and clicking on the icon in the taskbar via the GUI to log in doesn’t work – Check your network cards!
This is usually caused when Tailscale cannot tell which network card has priority.
On Windows:
Win + R //to open run
ncpa.cpl //to open the network settings
Select main network card
Open Properties, then IPv4
Click on Advanced, untick ‘Automatic Metric
Set to 10.

Try again. Chances are, tailscale will now let you login and generate the login page popup allowing sign on. Authkey authentication should also now work.
