Nginx with Odoo configuration: host not found in upstream

What should I change in the (almost) default Nginx configuration below to be able to open Odoo at http://erp.my-odoo.com, knowing that I've set the DNS erp.my-odoo.com pointing to Odoo server at 192.168.0.10 ?

/etc/nginx/conf.d/odoo.conf

# Odoo Upstreams
upstream odooserver {
    server erp.my-odoo.com:8069;
}

server {
    listen 80;
    server_name erp.my-odoo.com;
    access_log /var/log/nginx/odoo_access.log;
    error_log /var/log/nginx/odoo_error.log;


    # Proxy settings
    proxy_read_timeout 720s;
    proxy_connect_timeout 720s;
    proxy_send_timeout 720s;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;

    # Request for root domain
    location / {
       proxy_redirect off;
       proxy_pass http://odooserver;
    }

    # Cache static files
    location ~* /web/static/ {
        proxy_cache_valid 200 90m;
        proxy_buffering on;
        expires 864000;
        proxy_pass http://odooserver;
    }

    # Gzip
    gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
    gzip on;
}

This configuration gives me the error below:

$ sudo nginx -t
nginx: [emerg] host not found in upstream "erp.my-odoo.com:8069" in /etc/nginx/conf.d/odoo.conf:3
nginx: configuration file /etc/nginx/nginx.conf test failed
