Amazon web services – django static files are not loading on production server nginx

when I don’t specify my port number in my url, static files are not loaded in that case.
It works fine for xyz.com:8000 all the static files are loaded But when i use xyz.com, it doesn’t load any static files.
I’m using nginx server.

this is my nginx configuration

server {
    listen 80;
    server_name santhals.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
    root /home/ubuntu/santhals/myapp/;
}


    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}
