ERR_CONNECTION_REFUSED after changer domain IP

I changer my domain that was pointing to one droplet to another but im now getting ERR_CONNECTION_REFUSED since more than an hour, if i go directly to the ip address it work: http://139.59.225.139/

my nginx file is simple as follow:

server {

 listen 80 default_server;
 listen [::]:80 default_server;

  root /home/crashbdx/beta.sign-art.app/dist;
  index index.html;

  server_name beta.sign-art.app;

  location / {
    try_files $uri $uri/ /index.html;
  }

  allow 112.206.97.9;
  deny all;

}

Any idea? can it be the propagation even if it a DNS/IP lookup show the correct IP ?
