Eureka Service Discovery UnknownHostException

I trying Eureka Service Discovery for the first time and this is the problem I am facing.

java.net.UnknownHostException: banking-portal
    at java.base/sun.nio.ch.NioSocketImpl.connect(NioSocketImpl.java:567) ~[na:na]
    at java.base/java.net.Socket.connect(Socket.java:751) ~[na:na]
    at java.base/java.net.Socket.connect(Socket.java:686) ~[na:an]

My Eureka server is running and both of my applications are registered

But, while trying to hit the URL
"http://banking-portal/accounts/getById/{accountId}";
I am getting the above-mentioned error.

Please let me know what I am missing.
