I need to configure EKS kubernetes plugin in jenkins.

I set the eks url and credential for cluster in the global page.

When I press "test connection" button, I get timeout exception.

Connection to EKS cluster should be done via proxy.

The proxy define in jenkins in correct way ( under plugin -> advance page ). The test button under plugin -> advance page is working with EKS url ( I don't get timeout exception, get authorization exception and it's good )

How to configure the K8S plugin to take the same proxy definition like in plugin ->advance page?
