Hi, I put this software on the virtual machine. At the direct address-192.168.1.131:4567-there is a response, and at the external address-there is no response - 93.95.167.101.
There is also no response for the domain - cp.slainscraft.com
The firewall has a rule, tried to disable it, redirection is configured in the Internet center:
ID STATUS NAME Local Adress Protocol PortO PortIn
7 Enable Node 192.168.1.131 TCP 80 4567
8 Enable NGINX 192.168.1.131 ALL 4567 4567

I also tried reinstalling everything.
In config - "url": "http://cp.slainscraft.com",

server {
    listen 80;

    server_name cp.slainscraft.com;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://127.0.0.1:4567;
        proxy_redirect off;

        # Socket.IO Support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
