powerdns panel not run after install ngnix

[famaserver]

Hello
I have the same problem as this.
After installing pdns and its services, all services are properly active
But after the web server is working properly, the pdns panel is not loaded.
All services are active, including:
nginx
pdns
powerdns-admin.socket
powerdns-admin.service

But the admin panel does not open with port 9191.

Please provide us your nginx config files, your pda service file and logfiles of nginx and pda (only content depending on this problem) .

I watched its installation tutorial from https://phoenixnap.com/kb/powerdns-ubuntu and followed it line by line.

As long as the Python web server is running, the panel will open, but when ngnix is installed, there is no way to access the panel, but if we connect to the IP server with port 80, the ngnix welcome page will appear.

ngnix:

  listen *:80;

You have to create an upstream:

upstream pda{
    server unix:/run/powerdns-admin/socket;
  }

and use it as proxy pass:
proxy_pass http://pda

Do you introduce training in this context?
Or is there a reference link or source of an article for this?

Just a part of my personal working config ;-)
