Adding new load-balancer to kubernetes x509 certificate




I’m running a k8s cluster in AWS and I’ve created a new load-balancer that will be used to access the cluster via kubectl. I’ve update the kubeconfig with the new url but I run in to the following issue when trying to run any kubectl command:

Unable to connect to the server: x509: certificate is valid for…etcetc

I’m a bit unsure of how I can add the new load-balancer to the certificate or renew the certificate so that it includes it. Any help is welcome, thanks in advance! (edited)
