Kibana reverse proxy with nginx gives Empty Dashboard on Kubernetes

Hi

We have Deployed Kibana & Elastic Search on our Kubernetes Cluster. I want to access Kibana via my Nginx by configuring reverse proxy . I am able to configure the nginx.conf with kibana url but when I go to nginx_url/Kibana it gives me a White Dashboard ,no content on the web . It is Strange because i got it worked on my Local machine & it worked but same configuration on kubernetes giving me Empty response .

Below is my Kibana deployment file

apiVersion: apps/v1
kind: Deployment
metadata:
  #namespace: vpd-cluster-elk
  name: kibana
  labels:
    app: kibana
spec:
  replicas: 1

Below is my Nginx.conf file

metadata:
  name: nginx-conf
data:
  nginx.conf: |
    worker_processes  1;
    events {
        worker_connections  1024;
    }
    http {
        
        include       mime.types;
        default_type  application/octet-stream;
        sendfile        on;
        keepalive_timeout  65;
         # To allow special characters in headers
         
         
         ignore_invalid_headers off;

         client_max_body_size 0;

         proxy_buffering off;
         
         server {
         
            listen       80;
            server_name  _;
            
           location /app/home{
            proxy_http_version 1.1;
                       
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
            proxy_pass http://Kibana_Url:5601;
           
    }
           }
        
                            
            
           
    }
