Nginx Tailscale Auth

Greetings, I’ve been dealing with Tailscale for a few days and working on it. This is really enjoyable.

I’m trying to authenticate application access via Nginx for people joining the Tailscale network. I came across Tailscale’s own article on this subject and implemented this method on a test server, but with no results. Although I am networked with Tailscale on my own computer, when I test the nginx-auth instance it does not detect me in the network. How did you solve this problem or can anyone who follows an approach like me guide me?

Thanks in advance for your feedback.
