SEC_E_CERT_EXPIRED
SEC_E_CERT_EXPIRED means that a certificate received during security negotiation is outside its validity period according to the local system clock. The failure can involve the end certificate or another certificate needed for validation.
What to verify
- The validity dates of every certificate in the evaluated chain.
- The clock, time zone and time-synchronization state of the machine performing validation.
- Whether a recently renewed certificate was actually installed and selected by the server or client application.
Do not hide the problem
Ignoring expiration removes an important trust control. Renew the correct certificate and deploy its chain before retrying the secured connection.
