GKE on Windows: Failed to refresh token

When using Google Kubernetes Engine on Windows, the Kubernetes client
sometimes fails with the following error:

C:\...\node_modules\@kubernetes\client-node\dist\config.js:99
                            throw new Error('Failed to refresh token: ' + result);
                            ^
