My issue was related to expired certificates, which explains why my issue happened out of the blue.. It turns out the certificates has a 1 year validation period. This shouldn&rsquo;t be an issue since you&rsquo;re expected to upgrade your cluster every now and then. This is however not the case for me because my deployed software needs a specific version of kubernetes and docker with helm2 so I&rsquo;m not able to update my cluster until my software vendor supports a newer kubernetes version.</p>
