I am new the spring boot application

So currently client is calling a service I am debugging client and server both. I see client is invoking the service using HTTP INVOKER and service is not reaching to the server and there is a runtime exception "Could not access HTTP INVOKER remote services at [service call] nested exception is java.net.sockettimeout: read timed out.
And I see the error on screen and after few seconds I see msg is reaching to server for processing.

How can I fix this?
