The SpringCloud gateway is failing to call a Kubernetes service: "No servers available for service".

[oasis-zhou]

SpringBoot version: 3.3.3
SpringCloud version: 2023.0.3
SpringCloud Kubernetes version: 3.1.3

When calling other services within the same namespace from the gateway, either through OpenFeign or RestTemplate, the first call is successful, but subsequent calls fail with the following error: o.s.cloud.loadbalancer.core.RoundRobinLoadBalancer [USER:] [TRACEID:] - No servers available for service

When the configuration is changed to: spring.cloud.kubernetes.loadbalancer.mode = service, all the calls are successful.

The cache configuration when the above error occurred was: spring.cloud.kubernetes.loadbalancer.enabled = false. When set to True, the same error occurs after the cache expires in 35 seconds.

If you want us to diagnose the issue we are going to need a minimal reproducible example, like a github repo, with clear instructions how to see the issue. Thank you
