Which browser error indicates the SSL certificate is expired or invalid, as seen in the donations scenario?

• A. NET::ERR_CERT_DATE_INVALID
• B. ERR_CONNECTION_RESET
• C. ERR_NAME_NOT_RESOLVED
• D. ERR_CERT_WEAK_SIGNATURE

Answer: (A)

When browsers validate SSL certificates, they check the certificate’s validity period (Not Before to Not After). If the certificate is expired or not yet valid, the browser marks it as invalid for that site and shows a date-related error. NET::ERR_CERT_DATE_INVALID is the message you see in exactly this situation: the certificate’s date window isn’t valid for the current time (sometimes also affected if your computer clock is wrong). The other errors point to different issues—connection problems, DNS resolution, or a weak signature—not to the certificate’s date validity. So for an expired or invalid certificate date, this error is the correct indicator.
