Win 10 "Log In" button not doing anything

Windows 10 1607, Tailscale 1.8.3 - 1.8.5

After install, the “Log In” button does not pop up a browser window. The logs have lines like this:

{“logtail”: {“client_time”: “2021-05-20T20:57:40.342137-05:00”}, “text”: “ui: UI still alive.\n”}
{“logtail”: {“client_time”: “2021-05-20T20:57:42.2041477-05:00”}, “text”: “logtail: dial “log.tailscale.io:443” failed: dial tcp 34.210.105.16:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (in 21.004s)\n”}

I tried running “tailscale.exe up –authkey xxxxxxxxxx” as well - it seems to hang.

Hoping there are workarounds or additional diagnostics I can try. . .

Hello,

We have tested this on 12.8.5, and it works fine for us; for dig into the issue, can you please email your domain and Tailscale IP of your node to support@tailscale.com so we can review the log.
