Program shows long log output when server not available #9

When the API server is not available, ktop simply output a log message instead of immediately disconnecting

kubectl ktop

A better approach would be to stop sooner if the api server is not immediately available. Or, manage the UI better as a valid connection is being tried.

+1, we can simply error out: E0108 13:32:42.673484 network is unreachable: 10.84.90.84:6443.

Maybe adding some resiliency (retry after x secs) would better in this case.

This should no longer be the case with v0.3.0. Closing it.
