How to set up 2 servers on a local network on the same domain?

Question

Nginx

There are two servers under the same domain, united by a local network (s0.server.net and s1.server.net - on the phone), you need to configure s1 so that if it does not have the desired subdomain, then it transfers to s0. As I understand it, this can be done through proxy_pass, but it doesn’t work out very well for me, it gives a 503 error
. Settings s1:

worker_processes  4;
error_log  /data/data/nginx/servers/CCX/logs/nginxerror.log;
events {
    worker_connections  1024;
}
http {
    include       /data/data/nginx/base/conforig/mime.types;
    default_type  application/octet-stream;
    include    /data/data/nginx/base/conforig/fastcgi.conf;
    access_log  /data/data/nginx/servers/CCX/logs/nginxaccess.log;
    error_log  /data/data/nginx/servers/CCX/logs/nginxerror.log;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen 8080;
        server_name server.net *.server.net;
        root $subdomain;
        set $subdomain "";
        autoindex on;
        index  index.html index.htm index.php;
        if ($host ~* ^([a-z0-9-\.]+)\.server.net$) {
            set $subdomain /storage/emulated/0/www/$1.server.net;
        }
        if ($host ~* ^server.net$) {
            set $subdomain /storage/emulated/0/www/server.net;
        }
        location / {
            proxy_pass http://192.168.1.47;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP $remote_addr;
        }
        location ~* \.php$ {
            fastcgi_pass 0.0.0.0:9009;
            include /data/data/nginx/base/conforig/fastcgi_params;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_intercept_errors on;
        }
    }
}
