Spring Cloud Openfeign java.lang.RuntimeException: com.netflix.client.ClientException during feign client usage

We are getting Client exception when we try to use feign client. We have used org.springframework.cloud:spring-cloud-starter-feign:1.3.6.RELEASEbefore which was working fine. And we thought of migrating to org.springframework.cloud:spring-cloud-starter-openfeign:2.1.2.RELEASE. After migrating the library from feign to openfeign we are getting client exception on our system. And it seems like it is failing in openfeign library. Locally everything works properly. When we deploy it in Kubernetes cluster in dockerized way it is giving this error. Do we need to do some changes on our configuration to make this work? Any help would be greatly appreciated

Exception:

Comment From: geekpearl

@spencergibb Additional information on the issue:

Our feign client code looks like below:

@FeignClient(name="client1", path="/finance")
public interface CustomerClient {
//implementation goes here
}

our application yaml look like below:

ribbon:
  eureka:
    enabled: false
  eager-load:
    enabled: true
    clients: client1
client1:
  ribbon:
    listOfServers: https://url1:443
    ReadTimeout: 300000
    ConnectTimeout: 10000

And the url is resolved as http://client1/finance. It is expected to resolve as https://url1:443/finance

I have tried

ribbon:
  isSecure: true

It did not help me either.

Comment From: spencergibb

Do you have ribbon as a dependency?

Comment From: geekpearl

@spencergibb Yes. We are having "org.springframework.cloud:spring-cloud-starter-netflix-ribbon:2.1.2.RELEASE" as dependency in our project

Comment From: spencergibb

I'm afraid there's nothing here to help me determine your problem.

Can you provide a complete, minimal, verifiable sample that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.
