How do I receive system notifications of certificate expiration?

One month before the certificate expires, the SSL certificate management of this site will prompt the certificate expiration information. You can also use the message center to set whether to receive certificate-related system message notifications.
Note: 30 days before the certificate expires, the SSL certificate management of this site will prompt you to have a certificate that is about to expire. You need to reserve 3-10 working days before the certificate expires for renewal, in case the existing certificate expires before the certificate review is completed.
