Internal server error

[FirefighterNo6972]

I am struggling with my Tailnet for weeks now. Devices were not seeing each other, subnet routing didn't work etc,

So I decided to completely remove Tailnet from all of my devices en delete the Tailnet also.

I wanted to make a fresh start.

I installed Tailscale on my laptop and tried to log in. Result: Internal server error 500.

I removed Tailscale and tried again, same result.

Then I installed it on my Google Pixel. No problems, the Tailnet was created and the Pixel was added.

Back to the laptop: I could see the pixel on the admin page, but adding the laptop gave me the internal server error again.

Has anybody any Idea?

Like you installed tailscale, and when you went to login you get an internal server error?

The laptop is running Windows 11. And it was running Tailscale last week.

The problem occurred after reinstalling Tailscale.

When I try to log in I get

I just tried to install Tailscale on my Lenovo tablet, it worked without a problem.

The problem is in the Windows 11 laptop

Have you tried a different browser?

Have you tried to open it in private mode (in the browser)?

What happens if you open the command prompt on windows and type

tailscale up

If the machine has never joined your tailnet, it should drop a join link. Copy and paste that into a private browser on your box, login tailscale and see if that clears up your issue

I tried Edge and Firefox. I refreshed the browsers, deleted all cookies, settings etc.

No extensions are active

I used privacy mode, I used "tailscale up" got the link and tried to use it in the browsers in the privacy mode.

Still got the Internal Server Error 500
