Here's my spring config server bootstrap.yml

When spring boot client can not connect to spring cloud config on kubernetes. I'm getting this error from the log client on Kubernetes. But I'm not getting this error when I login directly into the client container.

Here's the log of the client. This time I've pointed it using the hostname with a service the I've defined for the server on port 32752. But it's still giving me the same error.

I solved this problem by deploying the config serve to another pod. The reason the client couldn't connect within the same pod (via bootstrap) is because the server wasn't ready.
