Connected but no access to docker services


i have an unraid box (ver. 6.11.0) with tailscale installed (deasmi template).
I followed the tutorial from ibracorp and connected my android phone.

I can ping my server and access docker services using the “tailscale ip”:port.
But it is not working if i try to acess with my domain running via cloudflare and nginx

Any clue where i fail?
