(Urgent) Unable to connect to the server: x509: certificate has expired or is not yet valid

Hi, I face the certificate expired issue, and I can not control the Cluster on Rancher GUI , the console of master server also can not execute any command(kubectl get node). May I know how to renew the certificate and resolve this issue? Thanks.
