问题 I've created a cluster on Google Kubernetes Engine (previously Google Container Engine) and installed the Google Cloud SDK and the Kubernetes tools with it on my Windows machine. It worked well for some time, and, out of nowhere, it stopped working. Every command I'm issuing with kubectl provokes the following: Unable to connect to the server: net/http: TLS handshake timeout I've searched Google, the Kubernetes Github Issues, Stack Overflow, Server Fault ... without success.
