Hi everyone,

Sorry for my english. My scenario like below ;

I setup my webserver in cloud and I have my ERP server running at different DC. The connection from cloud to DC is very fast, no interuption at all. When my customer access www.example.com it will show the website that i build in cloud (Webserver). Each customer have vpn access when they subscribe with us. So, when they wat to use ERP system, they need to connect to vpn first and they can go through https://erp.example.com. I configured NGINX to allow only server subnet IP and tunnel network subnet for VPN. The problem is when they click to login page, it will show error 403 not my html error page. I want it to trigger error page that I build in HTML.

My problem is it not show the error page (html) that I build. It wil show error 403.

Please anyone help me
