Can't access Nginx server from local network (LAN) - nginx

Question

I just installed Nginx and a service on port 8069. I able to access to my service from outside by using odoo.domain.com. But the problem is I can't access from local network (LAN).
If I try to access Nginx's IP then I can see Nginx default page but if I add ip:8069, it still not working.
Below is my Nginx config.
server {
server_name odoo.domain.com;
listen 80;
access_log /var/log/nginx/testing-access.log;
error_log /var/log/nginx/testing-error.log;
#return 301 https://$host$request_uri;
listen 443 ssl http2;
#rewrite ^(.*) https://$host$1 permanent;
