nginx. How to proxy requests from one url to another using different ports (SOLVED)?

Question

Nginx

Hello!
There is a server on which to deploy Nginx (IP1).
I would like to be redirected to another url (IP2) with a different port when accessing this resource on port 80.
I see solutions with proxy_pass, but the path is indicated there without specifying the port.
My config:

server {
    listen 80;
    server_name IP1;
    location / {
        proxy_pass http://IP2:1111;
    }
}

If you do not specify port 1111, then everything works fine. How to be, tell me.
