Link service deployment Kubernetes – Nginx

I have two services running on k8s and I am using an ingress to access my services. One of the service requires access to another view env but I added the cluster IP and the port of the required service but it seems to be unaccessible.

User Deployment yaml

...
         - name: WALLET_SERVICE_URL
              value: 'http://10.103.xxx.xx:30611'
            - name: WALLET_SERVICE_API_VERSION
              value: /api/v1
...
