Tailscale problem

Tailscale failed to login

So I got a new pi installed yesterday and I had Tailscale on my old pi but it didn’t work on the new one.

So I went to login.Tailscale.com and deleted the devices so I could just start from scratch. Also uninstalled the Tailscale add on from HA.

Rebooted HA and installed Tailscale again, clicked install and start with all the options enabled such as start on boot etc.

Then opened the web ui, clicked login and it popped up with failed to login: null is not an object (evaluating ‘window.open(url,”_blank”).focus’)

What can I do?
