So I have a service of my application and want nginx to proxy the connection to it. I used IP address to tell the nginx which is the Service Node port of the application (100.68.202.75). The issue is that when the pods starts it gives me:

2019/05/25 17:32:38 [emerg] 1#1: bind() to 100.71.178.70:443 failed (99: Cannot assign requested address) nginx: [emerg] bind() to 100.71.178.70:443 failed (99: Cannot assign requested address)

Application runs separately on a different deployment with a service. I just want to tell to listen for that service. So it can redirect the traffic.
