springboot Failed to load resource when behind Kubernetes Ingress / Reverse Proxy path

I'm using Spring Boot Admin 2.1.3 with Spring Boot 2.1.3.RELEASE

I've deployed Spring Boot Admin into a Kubernetes cluster. It if frontended by an Ingress (I've tried both NginX & Istio Gateway).

The Ingress uses path based routing, so URI path with /bootadmin gets routed to the Spring Boot Admin Service -> Pod -> container. .

The problem is that it fails to load static resources like CSS because it is not looking for them at base path /bootadmin. Not sure if there is a anyway to tell Spring Boot Admin UI the root context path for static content?
