Regarding Tailscale's compatibility with Ngnix Proxy Manager and Duck DNS

How to recreate: Install Ngnix proxy manager and any self-hosted web app [Nextcloud, Owncloud, Portainer] in my case Portaniner WebGUI and put Ngnix proxy manager in front of it by using Duck DNS as a dynamic DNS client and setting the record to the Tailscale IP of the machine then after doing all of this when I write the domain name in browser bar it keeps on loading forever with about: blank on the other hand if I write Tailscale IP a with the correct port it loads in a second

Hi, this should work. I do something similar with traefik.

Did you verify your DNS entry with dig or nslookup?
