X509: certificate signed by unknown authority

After some maintenance on Kubernetes nodes, which created new certs in Kubernetes I got:

Failed to provision volume with StorageClass, rpc error: code = Internal desc = Failed to create volume: … x509: certificate signed by unknown authority (possibly because of “crypto/rsa: verification error” while trying to verify candidate authority certificate “kube-ca”)

Is there possibility to re-import, and how, new certs to Portworx, without full reinstallation?
