You saw this line in the error message?

Unable to connect to zero, Is it running at serverip:5080

That’s the grpc port for the zero, but you can try to connect with curl…

curl serverip:5080

If it responds with an issue about the HTTP version, then there’s a route to that IP. If it responds with “Failed to connect…” then you need to solve the network issue.

This is k8s. If serverip is an address, it’s wrong. Addresses in K8s are created with svc automatically. If you use our example YAML for K8s this will be solved. If serverip is indeed an IP. We may have a problem there. Depending on the context, a pod cannot see the Cluster IP, only its pod context. Ideally, never use fixed names or IP addresses, as this is an orchestrator. Everything is dynamic, mainly name resolution by K8s internal DNS.
