I just formatted my computer and reinstalled Windows (Windows 7 Home Premium SP1), and when I try to visit certain websites (eg Wikipedia), the sites do not load. The sites fail to load in both Chrome and Internet Explorer.

In Chrome I get the error cert_date_invalid. When I manually check the security certificate, it says "The certificate has expired or not yet valid"; however, looking at the dates, the certificate appears to be valid for today's date (ie, the range of valid dates includes today), and the system clock is correct. Many other sites (eg Google) do work and the certificates show up as valid.

Windows Update gives me the error 80072EFE, which seems to be a connection error. I've tried restarting the computer.

  • What root CA signed the certificate? – Ramhound Jan 05 '22 at 01:57

    See if any of your system's trusted root certs have expired. Maybe run all Windows updates, in case Microsoft already issued an update for expired root certs. – Spiff Jan 05 '22 at 02:01
  • Windows update is not working, error 80072EFE. – Humid Morning Jan 05 '22 at 02:19
  • I checked the Wikipedia certificate and the root certificate was CA DST X3 and its expiration date was in 2021. I guess that's the problem, how could I fix this? – Humid Morning Jan 05 '22 at 02:25

    This answer should address your question. [NET::ERR\_CERT\_DATE\_INVALID and certificate is not expired](https://superuser.com/questions/1679010/neterr-cert-date-invalid-and-certificate-is-not-expired) – Ramhound Jan 05 '22 at 04:43

It turns out that the root certificates were out of date, as suggested by the comments. I downloaded the Windows update "Support for urgent Trusted Root updates for Windows Root Certificate Program in Windows" directly from the Microsoft site, which fixed the problem.

  • Can confirm this has worked for me. – nickpapoutsis Feb 02 '22 at 15:44
  • Worked for me too. Had to download and transfer to the box in question though. https://support.microsoft.com/en-us/topic/support-for-urgent-trusted-root-updates-for-windows-root-certificate-program-in-windows-a4ac4d6c-7c62-3b6e-dfd2-377982bf3ea5 – vr_driver Sep 08 '22 at 02:10
