What Can I Do If My SSL Certificate Expired?

SSL certificates have a validity period. Once a certificate expires, it cannot be used. Renewals are allowed only for valid certificates.

You can renew only paid SSL certificates you have purchased in SCM before they are about to expire.

To replace the certificate that is about to expire, manually install the new certificate on your server. A certificate application must be submitted to the CA when you purchase a new certificate or renew a certificate.

You can replace the old certificate with the new one once it is issued. The replacement does not affect services.

You are advised to purchase or renew an SSL certificate at least 3 to 10 working days before the current one expires.
After a certificate is renewed, the validity periods of the old and new certificates are described as follows:
- Details of new certificate not changed
  If the certificate details remain unchanged, the actual validity period of the new certificate equals to the remaining validity period of the original one plus the requested validity period of the new one. A maximum of 30 days can be counted towards the validity period of the new certificate.
  
  For example, assume that your current certificate expires on October 1, 2019, and you request a new one-year SSL certificate with the same details from the same CA on August 31, 2019. If the new certificate is issued on Sept. 1, 2019, it will be valid from Sept. 1, 2019 to Sept. 30, 2020.
  
  This rule is formulated, interpreted, and clarified by the CA. If you have any questions, we will work with you to communicate and negotiate with the CA.
- Information about the new certificate is modified during manual renewal. For example, the domain name, certificate type, or company name is different from that of the old certificate.
  The validity periods of the current and new certificates are calculated separately.
  
  The use of the new certificate does not affect the current certificate. The current certificate can continue to be used until it expires.
