Nginx and subdomains issue

Hi, Here's my configuration

server {
  listen 80;
   location / {
      proxy_pass http://123.456.789.10:8080/;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

Hints? TIA
