Xip.io not working with nginx proxy

Hi guys, I have a problem to access my apps using xip.io with ingress load balancer setup through rancher UI.

I’ve successfully get xip.io url and this url working internal, but from public i cannot access to this url. FYI I dont have static IP but I’m using ddns server to get dynamic ip and mapping to our domain.

I manage my domain in Digital Ocean and already pointing A record to our on prem server.
