This is the third time when Kubernetes starts to be unavailable for “kubectl”. Sometimes I cannot connect to the cluster using Kubernetes CLI and get the following errors:
Unable to connect to the server: dial tcp x.x.x.x:443: i/o timeout
Or
Unable to connect to the server: net/http: TLS handshake timeout
The indicator near the k8s logo lights yellow whereas it’s green when all Okey. When I try to add extra nodes it stucks in “loading” state without any changes. We rely on your servers and clusters, but it lets us down every week. On your servers, we host production environments of projects and monitoring infrastructure. I cannot Google any information about this issue. What do we do wrong? How to avoid these problems in the future?

Just experienced this now. This is severe. When a cluster is having issues, being able to connect to the master node to debug and repair is essential. I am running a 3 node cluster with production plan nodes.
Same problem. Tasks like “helm upgrade” for a simple Prometheus installation cause the DO k8s going yellow in DO panel and cannot get any answer to kubectl commands. There was not heavy use of k8s API.
It seems to me that DO k8s is not production ready yet.
The same issue, clusters change from ready to unready and no way to debug is available not even shell over the browser. Total invisibility on what is going on.
